Your idea for the scout transmission case sounds good! Those have studs that thread into the front right? I bet you could bolt it up just by drilling holes in the Pinto Bell. I don't think the Jeep input is going to work so well though. It's 1 1/8" vs. 1 1/16" so you'd have to find a different clutch disk. (According to this page anyway) I know the tip is longer than the Ford input, but I don't think it's any smaller. You'd have to compare it to the Pinto input to be sure. The Ford input shaft I'm using in my Jeep works fine, and the only thng I had to do was have a common Ford pilot bushing turned down to fit inside the flywheel. It didn't cost much to have it turned down and the Ford input is a whole lot easier to find than the Jeep input. If I had to do it over again, I would try your Scout case idea, but I'd use the Ford input again.
