In order to use the 4 cylinder tranny, you will obviously need to swap the bellhousing for a V8 model and you will have to either swap the input shaft or get a pilot bearing that is made for the swap.Now I have "heard" there is a standard pilot for certain years of S 10s that will work,but you will have to rerearch that.The prefered model does come from the 87-88 T/C or 87-88 XR7 Cougar.
