Jim yep I new the spline count was in the twenties, that trans is a world class out of a camaro. I did do the jeep input swap on another t-5 just haven't used it yet.
I also have one from an Astro van, with a 3.50 first gear. It has an input shaft that is the right length, no cutting, or grinding. The trans has the ford bolt pattern, so I had to get the bell housing off of the Astro van, it was on a 4.3 engine so it will bolt up to just about any chevy block after 1963.
