I'm wondering if anyone knows if there is a difference between 4x4 manual and auto trans crossmembers, frame braces, skidplates, and driveshafts. Thanks-Nick

 

Driveshaft is shorter on the Getrag
Skid plates are slightly different, but not sure if that matters...never put mine back on after the swap.
Crossmembers are different...they bolt into the same place, but the Getrag is beefed up a little bit more. I've used both with my 5sp swap to no ill effects.

Also worth mentioning the NP205 has a different spline count on the input between the two (ie an auto TC won't bolt up to a manual tranny).

 

By "beefed up" on the crossmember do you mean it was built up in height or reinforced? I have 5 speed trucks with the short and tall frames, and the tall frame truck(92 club cab) has a boxed out piece on top that the trans mounts sit on, presumably to keep drivetrain angle correct? My 91(shorter frame) doesn't have that. I'm more interested if there is any difference in height, mounting holes etc, in same year crossmembers because I have a couple of extra crossmembers and skid plates I'd like to sell, and I don't own any automatic stuff to compare it to.
