    Some of them bolted right to a TH350. In fact, that is the most common config in automatics. You just have to find one that came out from behind the TH350, manuals and TH400 205s will not work without trouble and $$$.

    Another option, since you'll have the whole truck, is to swap the transmission and transfer case from that truck into your K5. First gear in those 4-speeds is a serious granny low crawling gear. Of course, you'll have to shift gears for yourself then. [​IMG]

    you will need to have the input shafted chnaged and get a new adapter. If you find a used adapter it will be a lot cheaper and I think thatk30guy has one for sale. The input shaft itself, I think runs about $200-300..


    Then if you cant do it, you will need to have someone install it for you...
