finally got a tcase built for this. had to take the 31 spline input out of my parts tcase and put it in a tcase from a newer truck that was 34 spline.
bolted in with a clocking rig so it clears the crossmember and gives me a flat belly. made up some shifter linkage while at it
was able to get enough help and got the cab on, just sitting right there and have to figure out some mounting. right now its sitting to high in the back as its sitting on the tcase cause i clocked it up. thats ok as most of the floor on that side is rusty so will cut it out and build a new floor and make room for the tcase
