Re: 1947 Panel Truck Frame swap with ’88 k2500
After all the other fine work you have done, adding a strip of filler to the fenders to widen them would be easy. Then your wheel options open up and no worries about steering geometry upsets with scrub angles etc.

Re: 1947 Panel Truck Frame swap with ’88 k2500
how about trying front fenders from one of the "big" AD"s like a 3500(?). I hear they are about 3" wider each side over a 3100 fender.

Re: 1947 Panel Truck Frame swap with ’88 k2500
Thanks for the comments and feedback. I had the radiator mounted in front of the core support with the ’54 235, It should fit there with this 5.7. I may have a new radiator modified or built. There are a few issues with the radiator that I will look at. 3 core vs. 4 core. Vertical flow vs. crossflow. Location of the upper and lower ports. Copper vs. Aluminum regarding Galvanic reaction with the engine.
I would like to keep everything stock, or as much as possible on the body, and the drivetrain. There is already a lot of headscratching going on to figure things out. Moving the engine, or moving the steering gear would cause dominoe effects. That adds to the cost of the project, and this work is being done in a shop so I need to keep the focus on the big picture. I found a couple vendors that offer wheels with vintage looking hub caps, I may go that route, of get the clips and use my original hubcaps, but I will be driving this before that happens. I saw that Chevrolet did a frame swap a couple years ago. They widened the front fenders. I have considered it. The bigger truck fenders is another option too, I believe the hood would also be part of that swap since the rear lower corners of the hood are different on those. I am real happy with where the wheels sit now, so I’ll leave it at that. Things are moving along. The shop owner has his son’s working since one is a Barber and can’t work otherwise. I’m glad I can help support the economy during these trying times. The front sheet metal is being fitted. Time to get everything mocked up, so I delivered some parts last week. Awhile ago I picked up a new GM steering column from someone who gave up on a jeep project. While I was looking for similar builds, I saw on Old57’s build that he used Kugel Komponents Brake bracket. I called them and ordered separate Brake and Clutch brackets since they didn’t offer a separate clutch bracket. I need the clearance for the stock brake booster. Ordered on Tuesday, arrived on Thursday, Wow! I also went to the parts yard and cut a fuel filler door panel out of a Nissan, that was fun… I have been keeping busy figuring out a way to keep the stock speedometer. It just might work. I have a motor mounted to the back of the speedometer, and am developing code to make it work, so far so good.

Re: 1947 Panel Truck Frame swap with ’88 k2500
The grill is almost fitted. Some creative design for the core support. My idea was to use the stock radiator until I get a custom radiator built. Doesn’t look like it will fit in there now… I got some seats from a Chevy Astro. Mocking up the steering column, pedals, and seat.

Re: 1947 Panel Truck Frame swap with ’88 k2500
The steering column is in as well as the Brake and Clutch assemblies. We used a section from the donor steering column to join the GM column to the donor shaft, needed about 4”. We also took the hole from the donor firewall. The pedal assemblies are in place. Still need to put in the donor gas pedal, and the foot starter bracket. The gas tank has been repositioned a little forward and a little down for clearance issues. The fuel filler door is in place. It looks like the battery will sit under the passenger seat. The original location was under the passenger floor, but with the wider frame that won’t work. There is an access cover under the seat, the battery can be lowered in and rotated to sit towards the outside. The exhaust runs through that area, but there’s enough room for a battery. The other option is to have the battery high on the inner fender, under the seat is a cleaner option.

Re: 1947 Panel Truck Frame swap with ’88 k2500
The fuel filler door, looks like they had a hell of a time with that. It is what it is. We now have a bracket for the brake lever. Still working on the bracket for the foot starter linkage. The foot starter linkage will not include the arm that attached to the starter. It will just be the foot pedal and the curved bracket that it is attached to, and will mount on the body to actuate a momentary button. The plan is to have that done by next week and remove the body from the chassis to finish the welds on the body mount brackets.

Re: 1947 Panel Truck Frame swap with ’88 k2500
I have been working on the radiator issue. The stearing gear interferes now, and I am running the stock ’88 fan and fan clutch. I looked at using the original radiator shifted up or out at the bottom, there just isn’t room to go up much. I looked at using the ’88 radiator, I even tried a ’70 camaro radiator for fit as I read that might work. There are brackets behind the front grill that restrict that area. I drew up some plans and went to the radiator shop for feedback. They suggested I go with a modified downflow, mock it up in cardboard for fit. So that is what I did. My builder changed the core support bracket to accommodate a radiator. I drew up some final plans and am ready to go back to the radiator shop to have a custom radiator made. I will use the stock ‘50’s top tank (20”) and have the bottom tank cut down to just under 18”. There is a band on each side of the core, so the max width will be 18” with the core just under that. 25” tall with the frame and core support being different from stock there is room to go lower. We’ll use 2-row dimpled core, so I’m hoping it will be thin enough to not have to cut into the latch panel much. The top tank will be offset to the rear. I had been running a 235 inline six with the stock radiator mounted to the front of the core support, so there is about a 1 ½” cut out in the latch panel. The radiator should look right when in place. I’ll ask if we can fit in an oil cooler in the 2”x 18” gap.

Re: 1947 Panel Truck Frame swap with ’88 k2500
s10 swap guys run into the same radiator/steering box clearance issue and buy a 19x22 3 core from speedway. a word of advice, the lower hose connection points INWARD toward the crank pulley, some cut it off and turn it so it points OUTWARD toward the inner fender. in the past I used a 19x21 I found on ebay with a trans cooler in it and a straight lower hose connector.
looking good!

Re: 1947 Panel Truck Frame swap with ’88 k2500
The body is back off the frame, Body mounts are being welded on. The rear runningboard bracket conflicts with the spring perch. I collected the bed wood. I’ll glue up the cracks, clean it up, and finnish. The wood is in pretty good condition considering the age.
I had created a spreadsheet of parts early on for the build. I started with a Jim Carter catalog. Went page by page, adding to my spreadsheet whatever I thought was needed. The list is in no particular order, so it’s kind of jumbled, but it works. I then went through an LMC catalog since I had one in hand. Classic parts website next. I have a list of each part with the price difference. I found most of the parts from these three suppliers, but there are some things that I had to search for. LMC has some good generic options that I couldn’t find at JC, or CP, like aftermarket seatbelts. I added Ecklers, they have specific parts I couldn’t find elsewhere, such as hood hinge bolts. I’m adding a door lock to the drivers side and since I already have a left hand housing, I just needed the key cylinder. Chevs of the 40s has the left door lock assembly for 1941-1948 cars. I found just the cylinder at autopartsobsolete for $20 less than the whole assembly. I’m adding rear lights from a ’39 sedan. I found about 3 different makes from several vendors. Olddogstreetrods had the ones for me, but they did not include the gasket. I found the gasket at the Filling Station, they had some other interesting parts. I got a hood side emblem from them. At this point I wasn’t going through my entire spreadsheet to compare all the prices, just select pieces. ClassicPartusa has the doorlock gasket, and spring for the rear door lock rod. Simple little things, maybe I’m not looking in the right place, but I couldn’t find those parts elsewhere. I also read about an alternative part for the rear door bumper from 80/20 Inc. I had read about Steele Rubber, so they are on the list. I’m going to really have to want their product since the prices a quite a bit higher. I placed an order from Jim Carter, and Classic Parts awhile ago. Last week I decided to get more stuff, so I placed orders with Ecklers, Chevsofthe40s, and Filling Station. Now that the frame has been worked out it’s on to the bodywork, prep for paint. I may be getting ahead of myself, but I don’t want to wait for some parts that I could have ready to go.

Re: 1947 Panel Truck Frame swap with ’88 k2500
The frame is painted, next step is put the engine back on and reconnect the exhaust, and set up the parking brake cable. We’ll swap the left and right rear brake cables and locate the ends near the middle on a bracket. They will connect to the lever mounted to the right of the transmission. Painting the firewall and under body so the body can go back for the last time. We’ll jack the body up to reinstall the bedwood at some point after the bedrails have been painted. Meanwhile I have been working on the speedometer drive, and refurbishing the speedometer. The bedwood is in pretty good condition, so I’m reworking that.

Re: 1947 Panel Truck Frame swap with ’88 k2500
Thanks Docrock. I just read through your build, inspiring. I'm curious how you mounted the battery, do you have any pictures of that?

Re: 1947 Panel Truck Frame swap with ’88 k2500
I made a battery box out of sheet metal. Then I cut into the top of the inner fender. Dropped the box in and welded around it. Sorry no pics. Inside the wheel well you see the bottom of the battery box but it doesn't hit. There is a lot of room

Re: 1947 Panel Truck Frame swap with ’88 k2500
I decided to refurbish my old bed wood. The edge pieces are still black, the middle pieces are worn and cracked.

Re: 1947 Panel Truck Frame swap with ’88 k2500
The middle plank was split lengthwise and laterally, so required some creative clamping.

Re: 1947 Panel Truck Frame swap with ’88 k2500
I ran a sander over all surfaces, and then used water to clean all the wood. There was a gear oil stain in the middle of several boards from when I had a transission in the bed I think. I used some spray Bleach Cleaner on that area followed by a degreaser cleaner a couple times.
The wood glue shrank a bit, I used wood filler on the repaired cracks as well as the gouges. I shopped for a stainable wood filler. My first try left the filler standing out visually.

Re: 1947 Panel Truck Frame swap with ’88 k2500
I’m using Boiled Linseed Oil and Lampblack type of finish. I located 1 kilo of Lampblack for $60.00, could not find it anywhere. I did find a 4oz container of Marsblack at an art supply store so that is what I’m using. From what I have read, Lampblack is soot collected from burning Carbon Oxide, or Coal Oil. It may have a bluish hue after application. Marsblack is made from Iron Oxide, I think there is a reddish hue after application, but that may be from the wood or the Boiled Linseed Oil. I found some 2oz condiment containers at the grocerystore that work good for mixing small test batches. I got distracted and left the lid not snapped tight. I went back and shook it one more time to mix, and it slopped out on my work surface. The ratio of One Quart Boiled Linseed Oil to 1oz Lampblack, I figure 2oz oil to 1/8 teaspoon pigment. It looked good, but I want it darker, so my final mix is 1qt oil to 1.5oz pigment.
I mixed up some wood filler with pigment.

Re: 1947 Panel Truck Frame swap with ’88 k2500
The middle boards that were worn down took a lot of wood filler. I started with the darker filler. I got creative and used the untinted filler for the worn areas of lighter wood. As the bedwood was worn down over time, the lighter bands show greater wear. In the end, all of the filler became stained so it didn’t seem to matter if I tinted it or not. I did apply extra stain to the middle of the middle boards to compensate for the greatest worn area, it’s still lighter there, but I’m happy with the results. I decided to make a template of the bedwood for longbed panel truck, traced it on a big sheet of paper. This picture shows 2 coats.

Re: 1947 Panel Truck Frame swap with ’88 k2500
I put 2 coats of stain on all surfaces, and 2 more on the top surface. Finally 1 coat of polyurethane on the top surface, mainly to keep any pigment from leaching onto anything I put in the bed. I don’t know if that could happen, but I did that anyway. Reason for not covering all surfaces with polyurethane, the wood needs to breathe. The original design of wood planks and bed strips accouted for the expansion and contraction of the wood from humidity. I probably should have just used plywood since this is a panel truck. Plywood was used in suburbans to keep road dust out of the passenger area. I read about the 1 Qt. Boiled Linseed oil and 1 oz. Lampblack mixture, but looking at the original wood that is still black, I think there was a lot more lampblack, it is a solid black.

Re: 1947 Panel Truck Frame swap with ’88 k2500
I went to the shop a couple weeks ago. The engine is back on the frame. Firewall is painted. I’ve told the builder to wrap it up. I’ll be hauling this home soon to take on the wiring etc. Once I get it home, progress will take a slower pace as will the outpouring of funds(my primary objection). I have decided to tackle the exhaust myself. It looks like the original hanger can be used and the pipe will be extended behind the muffler. As you may be able to see in the picture it only took cutting it up to figure this out. Actually looks like it originally dumps in front of the rear tire, so may not need to be extended at all. These little side track issues add up when it’s all billable time, just the nature of the beast. I’m not saying I could do it better myself, but I don’t know if I could do worse… I checked in yesterday and the body is on the frame. The lower rear corners are being repaired where the only rust through on this truck is. There is a significant dent above the drivers door, and a dent in the hood. There is also a crack in one of the rear doors. Once this body work is done, I’ll take it home.
