Not bad gaps. I took the rocker off and it was a GM replacement. Even had the sticker inside. So I cleaned it up and am going tot reuse it.
I the picture the rocker is not seated all the way. The bottom gap is not that big.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Same thing happened to the passenger side of my cab. The top rubs the pillar with a huge gap at the rear. Previous owner did a rocker repair and I suspect the rear of the cab sagged when he cut it out. I believe the same thing has happened here. Cut loose the rear of the rocker and also where the cab meets the floor. The front of the cab will have to be pulled forward while the aft is picked up. Not sure if this makes sense but it should close up that rear gap and give some room in the front. Then the door will need readjusted. I haven't repaired mine yet but I think I'm gonna use a porta power in conjunction with cargo straps ,pushing and pulling. I hope some of this made sense:lol::lol:

Re: Project 68 k10 LWB..aka "The Hulk"
 

Good morning and thank you for the comment.
Yes I understand as I was thinking the same thing. (Great minds think alike and there are a lot of those around here.) That was one reason I hung the door and started aligning before welding anything. I was able to move the back of the cab, rocker, and door around. I did align everything yesterday and get it welded in. The gaps are a lot better. I am going to open up the hinge holes to allow the door to go back towards the latch this will also help out with the top of my cab and window frame.

Now that I am about down with the cab corners and doors. Now on to the filling holes on the firewall and cut the low hump out and install the high hump. Once this is done I am going to put the cab on the frame and see if everything clears before I send the body off to get it body worked.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Here is a picture of the door cab gap after all the adjusting. Not to bad.
But had enough with the cab corners and doors so decided to take a break and work on the center hump.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Had to make sure that it would fit. I did have to bend the seating area to match the trans tunnel curvature.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Outlined the high hump location on the floor. I will cut about 2" inside the black lines and will drill the holes for the bolts. I am going to weld nuts on the body and use button head bolts on the inside to hold it down. I think 5/16" is original. I may use 3/8" though.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Made the filler piece to fill the stock transmission shifter hole.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Got the filler piece welded up. It got late last night and cold so I forgot to take a picture after it was ground smooth. The wife is going to hang with a friend so I am going back to work on the truck.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Worked on making sure the doors,fenders and cowl fit. I was suprised how well it fit, or course the cab is not on the frame but we got an idea. We made sure the front fenders and grill were square with the cab according to my measurements I was off 1/8" on 1 side which makes is actually 1/16". I am very happy with that now I hope it stays that way after it painted.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Worked on welding up all the unwanted holes in the firewall. I did not want screws sticking through from the steering column grommet. So I threaded the hole and installed 10/24 studs in and welded them up.

Re: Project 68 k10 LWB..aka "The Hulk"
 

This is what it looks like from inside the cab.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Time to clean up from the past couple days in the shop. Feels nice to almost be down with the metalwork on the cab.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Picture of the firewall before I grounds down all the welds. OH and I did cut the fuse block bulkhead whole and drilled the mounting holes.
The painless harness I installed before used long bolts to mount to the firewall. The American auto wire harness uses long wood screws from inside the cab towards the firewall. Looks like I am going to get long bolts or maybe even weld studs in like I did for the column mount.
Has anyone welded studs to the firewall for the fuseblock bulkhead?

Re: Project 68 k10 LWB..aka "The Hulk"
 

I like the 10/24 studs Nice job ! What did you decide for the fire wall insulation ?

Re: Project 68 k10 LWB..aka "The Hulk"
 

Thanks
I am thinking lizard skin spray on liner or dynomat or equal.

Re: Project 68 k10 LWB..aka "The Hulk"
 

I don't want to have a bolt or screw through the firewall for the fuse block so I used 1/4-20 x3" countersink machine screw. I used a half inch nut as a spacer to tighten the counter sink bolt to create my own counter sink in the metal. Then ground down the counter sick head and welded it in.

Re: Project 68 k10 LWB..aka "The Hulk"
 

The inside studs.

Re: Project 68 k10 LWB..aka "The Hulk"
 

With the fuseblock in place.

Re: Project 68 k10 LWB..aka "The Hulk"
 

The firewall with the initial grinding. Now I need to finish the rest of the holes that I welded up and then that is complete.

Ok now what to do next???

Re: Project 68 k10 LWB..aka "The Hulk"
 

Excellent work as usual Scott!

Re: Project 68 k10 LWB..aka "The Hulk"
 

That is a great idea on the fuse panel mounting. I'm going to have to steal that idea if you don't mind :D

Project is coming along real nice!

Re: Project 68 k10 LWB..aka "The Hulk"
 

By all means use away.
And thanks for the Comments

Re: Project 68 k10 LWB..aka "The Hulk"
 

Has anyone ever removed the gas pedal bump or raised mount area in the floor? I was thinking about cutting it and folding it down to the same as the rest of the floor pan.

Re: Project 68 k10 LWB..aka "The Hulk"
 

I left it in on my cab.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Did you just put bolts in the holes or weld them up?

Re: Project 68 k10 LWB..aka "The Hulk"
 

Had a few minutes this evening so I cut the low hump out and got the high hump installed. I am going to weld 3/8" nuts to the floor and use stainless steal Allen button head bolts to hold it down. What sealer do I need to seal the high hump to the floor pan?i

Re: Project 68 k10 LWB..aka "The Hulk"
 

Also drilled a hole for the driver door jamb. This hole is behind the driver AC vent location. If I want to run wires to the door I can just add a conduit from the jamb to the door. Via a conduit.

Re: Project 68 k10 LWB..aka "The Hulk"
 

The passenger side does not have a location preset like the driver. So I went above where the AC vent would go.

Re: Project 68 k10 LWB..aka "The Hulk"
 

I just left the holes for now. until I install the gas peddle for my LS engine.

Re: Project 68 k10 LWB..aka "The Hulk"
 

3M has a product to seal the cover. I think GMC Paul or LMC caries it.

Re: Project 68 k10 LWB..aka "The Hulk"
 

I think the factory just plugged the holes with some pan head screws originally. You are making everything so smooth it would not surprise that you guys might smooth that also!

Great job on the high hump we welded a square nut on our c10 project prior to cut out similar to what GM had used in our high hump RV cab. I'd like to know what that 3M product is as well?

Re: Project 68 k10 LWB..aka "The Hulk"
 

I was able to take a picture of the buys I welded to the underside of the cab for the high hump. I used 3/8" flanged nuts.

Re: Project 68 k10 LWB..aka "The Hulk"
 

That's a good idea, just needs to stay put if the high hump was ever removed again.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Got some Raptor liner for the underside of the cab. Oh and some of there Grip prep.
I was able to Rust Mort all the cracks and crevices on the cab. I also DA'ed the underside with 80 grit. Have a couple questions for you guys.
1- do I need to seam seal the underside before the Rapter coating?
2- is there anything I need to do to the underside before I coat?

Thanks guys.
Scott

Re: Project 68 k10 LWB..aka "The Hulk"
 

Not being a body guy my first thought was to wipe it down with wax and grease remover. I also think when i had a Rhino liner installed they used scotch brite on the surface of the paint.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Hey swamp rat thanks for the tip. I will make sure to wipe it down

I have been working on the original 68 k10 (Hulk) Planned on building a small block and installing the 90' burb 10 bolt front since it is a 3.73. I figured I would replace the bearings and freshen it up. I plan to put power steering in also. Since I had everything to do it I figured what the heck.

I am rebuilding the motor out of my sons yellow 70 that I took out to do the LS swap.

Probably going win a 700r4 and a 208/241 t case.

I did however get the new drive shaft installed on the truck that I have been working on in this thread.
Pick tut from the top.

1970 motor on its way to the machine shop.

When we started this truck project I took my son to my shop and took some rubber made tubs off the rack. Opened them up and had all the top end parts still in the boxes. The receipt was even in he box it read 1997 my son was born on 1998.
Polished and ported vortec heads, Nice cam and lifters double row timing set, roller rockers. Etc. basically free since I bought it back in the day.

Re: Project 68 k10 LWB..aka "The Hulk"
 

Came to the game late on this build. Great detail and enjoyable to read. I'm subscribed!

Re: Project 68 k10 LWB..aka "The Hulk"
 

Hey dug224
Thanks for checking out my build. Between my others sons 70c10 this hulk project and the original green hulk truck. I have been very busy. Just bought another k10 running and driving k10 for 500$. Going to clean it up and sell to make a few bucks to fund the build here.

See ya!
