1G Help with 4g64 swap to 1g auto

[bob123131]

So i have a whole bunch of projects going but only running veichle is my shop truck that gets 10mpg. So i just want to get something running. I have a 90 auto awd with blown motor and a 4g64 setup in a gs spyder with no title. I want to put the 4g64 in the 1g and keep the awd and do manual conversion. So what tranny and transferace do i need to maintain all the right gear ratio's etc. I have a 22 spline now on the auto 1g.

I believe from what i have reasearched what will work best is.
95-96 awd trans- i believe later some stuff changed, and i want 2g as i know i can get it all to work with the 4g64
23 spline transfercase

Does that work? or

90-91.5 tranny with current tcase, but will that all bolt right up to the 4g64.

Tranny gear ratios for DSMs

You will have to change everything to swap from auto to manual, or else have a custom gear made and installed. Remember the rear diff is different too.
