Some REAL PROGRESS finally; got the transmission back from the shop a few days ago. Long output shaft and housing swapped over to the new case, new input shaft bearing retainer, new front & rear seal, new brake shoes. Gave the pilot bearing a little bit of grease and installed the transmission back onto the engine, then installed some mounts and threw the engine into the frame. It's bolted up, transmission mount and crossmember are in place, it's ready to start hooking stuff up to it.
And so I can start hooking stuff up, modified the firewall hole for the harness, since the '96 harness needs a larger hole. Made a template from the donor truck and cut it out. If I'd looked harder at the connector I'd have made my cut a little different and not bothered with that diagonal cut, but no biggie, it's like factory, and fits great:
I still need to enlarge the hole for the clutch master cylinder and drill the new bolt pattern for it. They gotta change everything, right?
Maybe next I'll try moving the fuel hard lines over from the '96 and swap its fuel pump over to my '92 cab & chassis sender/tank and install the tank. With that and some harness installation it should be ready to fire up. Plenty more work after that, though.
