Oh, good to know. I have the same compressor (KMS Tools jobbie). I may wait for a sale at PA then, for the blaster.

Re: 66 GMC Long to Short LS Swap

Impressed with your progress on the metalwork! Great idea with the enclosure for the sand blasting. Good solution on the outer rear of the cab (finding a new back for it). I have a similar issue. Was thinking I should buy a shop press, create a press brake, and make the bends in sections. The other solution I was thinking about was maybe a bead roller with a tipping die.

No, but that would have been a lot simpler! I used evaporust, then a rust converter, then paint.

Re: 66 GMC Long to Short LS Swap

Passenger floor is all finished up



Cut the bottom off the back of the cab, its all rusted from the inside out. Started cutting the back of the floor out to be replaced. Also removed the drivers side rocker.

Re: 66 GMC Long to Short LS Swap

Replaced the drivers side rear door pillar bottom with a piece I cut out of a donor.



Blasted the back side of the cab and floor and started on replacing the rotten metal on the back of the floor where it meets the cab.

Re: 66 GMC Long to Short LS Swap

Thanks Notch! For a while there I kept thinking "what am I doing here, just find a new cab". Was a little overwhelming at first but I have learned a lot as I go. I just keep plugging away, little by little. I feel like have the worst of it behind me. Drivers side should go a lot smoother. Glad I put in the work to save this old truck.

Re: 66 GMC Long to Short LS Swap

Replaced a bit more of the back of the floor pan. Had to cut another section off the back to get access to make the repair, then weld it back in



Sliced the bottom back off the donor cab. Drivers cab corner is pretty good, but not so much for the passenger side.



My original plan was to use a whole replacement cab corner, but after comparing it with the original I could see it was going to be a lot of work to reshape the replacement. I decided to use the one from my donor. I knocked out a bunch of dents and used a small piece from the patch panel



Hung the door and fit up the rocker. Started fitting the cab corner. Have to drill some holes for the spot welds and it will be ready to weld in.



Fit up the drivers side cab corner and the rest of the back. Looks like it will work well. Have to wait until I have all the drivers side floor and braces done before I weld this stuff in

Sucks the re-popped stuff is that far off. Lots of extra work sometimes....
Impressive effort on your part for sure!

Re: 66 GMC Long to Short LS Swap

Cab corner is welded in. Started working my way across the back of the cab. There is one small section that I couldn't salvage from the donor that I will have to fab.



While I was welding along the back of the cab I ran into a pocket of aluminum which instantly melted and made a mess. No idea how or why it was there?

That was most likely lead from an old repair back when lead was used. Nice work on the panel replacement and welding

Re: 66 GMC Long to Short LS Swap

wow great job but that led is a bummer it will be another education for us to learn how many ways to fix that? what's your choice. cut it out past the led? won't the led contaminate the steel where it's tined to weld or the steel to thin if you grind to far. iv seen led .25" to 10" wide depending on who did the work not the work needed. Thanks for the story,the pictures,and the time.

Re: 66 GMC Long to Short LS Swap

Well I ordered all the patch panels to start working on the drivers side floor, pillar, kick panel, fire wall. After waiting three and a half weeks they finally show up and the floor pan is wrong, so back it goes and I'm waiting again. In the mean time I finished up the last piece on the back of the cab.



The area above the windshield where the seal sits is rotten on my cab. I've been searching for good deal on a cab to cut up and use to repair that area. Finally found one suitable for the repair, ended up getting a set of fenders as well. My fenders were beyond repair. Didn't really want to use repop's so I was happy to find this set. Small patch panels on the bottom and they will be good to go.



I've never been a fan of the GMC gauges, and since the donor cab is a chevy I decided to swap dashes. This will let me use the Dakota Digital set up. Got the GMC dash removed, will be able to take care of some rust that would have been impossible to get to with the dash in.



My cab hasn't been in good enough shape to move since I installed the LS into the chassis so I haven't been able to check that the cab fit. I dropped the donor cab on the chassis to save space in the shop. Motor has tons of clearance to the firewall, probably 2 1/2 inches plus. I think it looks kinda funny, would look better tucked back into the firewall a bit more. What do you guys think?

Re: 66 GMC Long to Short LS Swap

The farther back with the engine as you can is better for weight distribution.

Re: 66 GMC Long to Short LS Swap

While I agree with Captain, yours looks to be the same place as mine. Truck drives fine, but I have not driven it much and not at all over about 40 mph...

You can see it here in Post #67, not the best picture but looks about the same distance as yours.

Re: 66 GMC Long to Short LS Swap

Got to work on the drivers side after receiving the correct floor pan. Fit up and welded in the front lower pillar and kick panel pieces. Had to replace a section of the front to rear brace.



Started fitting up the floor pieces and ran into alignment issues. Had to take a section out of the outer floor piece on one end to get the depressed groove to line up. Then had to add it back in on the other side. What a pain in the butt!!



Finished up slicing and got the outer floor welded in. Got the front brace fit up and ready for welding as well.

Re: 66 GMC Long to Short LS Swap

Truck time has been pretty limited lately but I keep plugging away bit by bit. Finished up the rest of the drivers floor and the cab braces. Had to remove the gas tank bracket to fix some rust underneath. Coated inside the existing braces with rust encapsulator.

[IMG][IMG][IMG][IMG][IMG]

Drilled out all the spot welds and removed the dash from my chevy donor cab to swap into my GMC. Also cut out the area above the windshield to be used as a patch panel for my cab.

[IMG][IMG][IMG][IMG][IMG][IMG]

All this rust repair is starting to get discouraging so I am going to take a break from it for a while and work on some mechanical stuff. Going to rebuild the rear end with a posi carrier, new ring and pinion, and all new bearings. Adding a rear disk brake kit from CPP.

Re: 66 GMC Long to Short LS Swap

Thanks Notch, using this set i bought off Amazon. Still on the first cutter. Must have drilled at least 150 spot welded so far.

Re: 66 GMC Long to Short LS Swap

Picked up a set of GM transit wheels along with some cheap take off tires to mount on them for now. Needed a bigger wheel to clear the disc brakes. I wanted to use wide white wall tires, but they are so limited in sizes. Saw this done on another build by 19SIKtySix and loved the idea. Painted outside of the wheel to mimic the wide white look with a low profile tire. I will eventually get them powder coated.

Re: 66 GMC Long to Short LS Swap

Got some time to work on the truck today. Plumbed in the fuel system with stainless braided PTFE lines and AN fittings from a local company called Hot Rod Fuel Hose.Really nice stuff!



Found someone local to reflash my ECU



Pulled the rear end and started tearing it down. Was hoping to find 3.73 gears but they were 4.10. Ordered a 3.73 set to go with the Yukon Duragrip carrier and master rebuild kit. Removed the drum brakes to make way for the new CPP rear brake kit. The passenger side rear drum was worn all the way through, nothing left!

I appreciate you posting that. I don't have a horse in the race, but I still like to steer people in the right direction. There are some that argue they all come from the same place but with different stickers. I would concede and say that may be so, but the TriPlus / KeyParts are an obvious better quality. There's a thread in these forums where pictures are posted showing the obvious differences.
