correct me if im wrong but i believe the spline count on your t-case is different than whats on the NV4500, somethin to think about aswell

your th400 205 will work cause if you get a chevy nv4500 you have a 32 spline input on your case, unless you get a dodge which will have a 29 spline output shaft then you will need to get a dodge np205 input for your case. Im always rebuilding these nv4500's im building one right now for my rig ill keep an eye open and i do sell my rebuilt ones for 1300$ which is less by about 500 - 800$ for rebuilt from other places. look for a 93-94 nv4500 chevy since they have a great 6.32 bull low or you can go newer 95+ which have a 5.38 bull low but they all are syncro'd and just a great tranny in my opinion but they are heavy 200lbs empty!!! and they take expensive GM syncromesh fluid which is like 25$ a litre
