Ok, I think I have found my answer to my question searching through old posts, but before I celebrate I want to make sure I'm on the right track and anyone’s help would be very much appreciated. Ok here goes, I'm going to get a nv4500 for my burb, I want to put a np205 behind it, but my question is, I just recently tracked down a np205 it's in a 88 1/2 ton chevy pickup with a turbo 350, I want to know if I could use it and how hard would it be to make it work, buying a $500 dollar adaptor is out of the question, but this is what I found in the old archives. _____________________________________________ Re: NV4500 - Anyone running one? Which T-Case? You can also bolt any 6 bolt style 205 up to it! 32 spline of course!!!! Re: NV4500 - Anyone running one? Which T-Case? A 85-91 NP205 will bolt on with a couple of mods. 1. 80-84 32-spline "short" input shaft 2. Notch the extension housing for shifter rail clearance. _______________________________________________ So does this mean I can use the np205 out of a 88 1/2 ton pickup that originally had a turbo 350, with a Chevrolet nv4500 with a little modification? Just want to be sure about this before I spend the cash on a np205 that I might not be able to use. Thanks allot to everyone.
