That's interesting to see. Sorry, I'm no help with it. The bumper looks good!

Dont forget to tie up the knock sensor wiring. I failed to secure mine and it rubbed through on some metal (Im guessing the fuel rails) and was shorting out popping the 40amp fuse for the ecu.

Re: 1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!
Got into the suspension a bit since it’s been raining the last few weekends. New front springs, went to 8600lb GVWR since the rear was already done long ago.
 Out with the old!  In with the new!  Passenger side   All installed!

Keep it up. This is one of my favorite builds to follow.

Re: 1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!
Finally! Both driveshafts are finished. The rear was rebuilt, the front is nearly all new. It might actually drive!
 The front axle needs to be rebuilt before any serious movement happens. It’ll be getting new ball joints, new brakes, new axle seals, and new wheel bearings. I scored this OTC axle socket kit for $50 on FB!

Re: 1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!
Down to buttoning up a lot of the little things now.
Installed the hood back on, and aligned!  The glove box door was broken off at the hinge, so it’s getting a new one.  New part in!  Utilizing one of the cutouts for the Holley USB cable.   And with the final touch of the original Owner’s Manual, it’s done!  Installed the floor mounted high beam switch.  Ran the wires for the speakers and dome light.  Mounting the new rear speakers in their housings.   Left and right rear speakers installed!

Re: 1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!
Getting even closer here!
New front bumper brackets showed up from LMC. Very good fit and quality!  Picked up some stainless carriage bolts and hardware and mounted the bumper.  The hood is looking pretty ratty with the rusted out front section, but we’re going to make it look slightly better in the meantime before I replace it.  Desecrating some old valve covers.  One side in!  Also ordered a front axle seal install tool. For $31, it wasn’t worth screwing around without it.

Re: 1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!
I totally forgot about these heat shields. Cleaned them up and bought some stainless hardware to install them!
   Getting very close to being done under the hood!  I picked up a different rear bumper in chrome instead of painted. Also installed stainless hardware on the mounts. Ordered new license plate lights as this takes a different style.  The shop is currently a disaster, but the truck is coming together!

Re: 1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!
I picked up a new wiper motor because the old one quit working.
 Turns out the new motor didn’t solve the issue, nor did a new switch. After a day of troubleshooting, it turns out the blue wires were swapped in the new harness!  New wiper motor in and all wires where they are supposed to be!  Installed all new wiper washer lines and filled the tank!  Next up, finally rebuilding the front axle!  Hub and rotor removed  Rotor and bearings are well worn due to improper hub nut adjustments.  The calipers are showing their age also  Drivers side!  Even the spindles are damaged beyond repair from the loose bearings  U-joints are completely shot  Everything all apart!  Time for some new parts! Rotors and bearings  New calipers and pads   Removed the carrier and old axle seals, cleaned the housing.  New axle seals!   Pressing the new seals in! This tool was worth every penny  Carrier reinstalled  New spindles  New hub nut kit  New U-joints installed in the axle shafts  New ball joints installed in the knuckle  New rotor and caliper installed   Hub installed  Ball joints installed in passenger side knuckle  Knuckle installed to axle housing  Axle shaft and new spindle installed  Backing plate, rotor, and caliper installed.  Also installed the new trailer brake controller under the dash.

Glad to see you still plugging away! I just put a new Borgeson box on my Z28. Very good product!

Re: 1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!
I’m glad to hear that, I’m hoping it will be a worthwhile upgrade even on a 3/4 ton truck!
I got the tires mounted on the rims and balanced last night! New wheels are going to really make it stand out! I’m still disappointed that I can’t find 16.5’s anymore, but I’ll save the old wheels to maybe go back on in the future.

Re: 1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!
Getting close to the last of the needed parts! Pretty much down to rear brakes and shocks at this point!
 New rear drums!  New rear shoes!  New rear hose and hardware kits!  New wheel bearings and wheel cylinders!  New axle gaskets!  Drums painted!

Re: 1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!
Getting down to the little things now!
Ran the vent lines for the fuel tanks and rear axle.  Ran the harness for the new license plate lights.  Adapter for the 7 pin trailer connector.   Made an interior harness for the trailer brake controller that tied into the brake light switch.  Made a circuit breaker block for the power feeds for the 7 pin and brake controller.  Driver front brake line was pretty rusty looking at the fitting, so I made a replacement.  Perfect fit!

Re: 1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!
Started on the rear brakes today. Didn’t make it that far, mostly because I could’ve sworn up and down that I had 13” brakes, but turns out that I actually had 11” rears. Instead of returning all the parts and going with 11”, I’m going to locate the 13” backing plates and end up with a better set of brakes!
The original ones were destroyed…    Both wheel hubs stripped. Probably going to take these into town with me and have them hot tanked since they’re pretty nasty.

That's the 11in "oil bath" RPO code, haha

Re: 1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!
Yeah no kidding.
I’m not sure if I mentioned this earlier, but for some reason I’ve had an interference issue with the hydroboost and master cylinder. I’ve had everything apart several times and can’t find any issues, so since I’m into the brakes now, I decided to just make a shim to gain the proper clearance back. Sheet of aluminum measuring .058”. I used an SBC thermostat housing gasket as a template and just moved the holes out a little bit for the booster bolt pattern.  Perfect fit! With the shim in place, I can measure .007” clearance now between the pin and piston.  Still not sure why there was a clearance issue, but this turned out to be a nice solution!

Interesting, so was it applying slight pressure to the MC without that shim?

Re: 1978 Chevy K20 longbed with nearly 500,000 miles! LS Swap begins!
Yeah, noticeable enough that I could slide the master cylinder onto the booster studs and seat it by hand and have nearly a washers’ width of gap between the two flanges once the pin touched the piston. I could feel it pushing the piston in if I pushed the master cylinder the final bit manually.
