I currently have a 4x4 1985 GMC Sierra with a tbi engine that has a carb on it and a sm465. I have available to me an NV4500 and transfer case from a 92 6.5. And I could easily get my hands on a nv3500 if I needed. So my question is what all will I need to complete a swap to one of these transmissions? Clutch, flywheel, pressure plate? Can I use all of that out of the 92? Is my driveshaft I currently have in the truck going to work or will I have to get a custom one? Will my current slave and master setup work for one of the NV’s?
