Re: 1976 CCSB Duramax Project #trucknamedsue

whelp, finally time for a decent update. Got my next order of laser parts in, wrong material but I used it anyways. I prefer to work with P&O plate but for some reason the laser shop thought standard A36 black plate was a perfect substitute.

so anyways, I used it all just cleaned it well with a scrubber wheel and alcohol before welding.

Pallet of parts-


all of these parts are rear end parts, so I started with the frame side 4 link brackets.

bent some metal and getting fit up, the aluminum bushing spacers are critcal-








bottom axle saddles bent and fit up. These have shock mounts and sway bar mounts integrated.-






upper bag brackets- also hold bump stops, upper shock mount and sway bar end link. started by bending out all these pieces-










machined the centering pins for the rear axle 4 link/bag brackets out of chromoly rod.


fitting up the axle side brackets-
















frame side brackets fitted-


inner stiffeners/gooseneck mounts-


gooseneck crossmembers. I really like how the transition/gussets worked out.






building out the 4-link and panhard. All the tubes are cut, faced flat, weld prepped, and drilled for plug welding. Quite a bit of work. They are tac'd up now, waiting for final welding until I am 100% on lengths.










with the rear end linked and sitting on the airbags, the engine and trans was able to be set back in to keep mocking/measuring and working with the CAD model.










so that's pretty much caught up to current. Just a ton of fab work, but making steady progress.

Will post some more in a few days.
