Re: 4x4 Stk. to Auto ?

All of the factory 4X4 AT linkage is different that 2WD due to the enging sitting much further back than 2WD. I suppose you could modify a 2WD set but it would be much easier to find a factory 4X4 setup.

Along with the flexplate you will need the flexplate to crank bolts, torque converter bolts, Yes the AT starter is different than the 4spd one.

The transfer case cross members are the same between AT and 4spd.

You will also need an AT steering column, transmission cooler lines and a radiator with internal cooler or an aftermarket external cooler, change out your underdash wiring harness or modify to include a neutral safety switch and relocate the backup light switch wiring. (if your not leary of digging into wiring its a fairly simple thing to do).

You will also need to plug the old 4spd shifter hole in the high hump, or swap it out with one from an AT 4x4 truck.

I am not 100% positive on the same driveshaft length. the yolks are the same if the AT setup you have is 1/2 ton.. 3/4 tons used a larger rear yoke and U-joint.
