Ok heres the scoop My buddies got a th 400 out of a cj that had qaudra-trac. He swapped out the shaft to run a dana 20 t case so its set up right now just like it came out of a waggoneer. That being said I have a viable tranny canidate to replace my 904 in my 401 gremmy. What I need to know is what other components do I need? I know I need a tailshaft off a GM car but what years did they come in? Also my 401 was originaly mated to a th400 in the jeep I yanked it out of. So I have the correct flexplate already and now I need a tourqe convertor. Anyone have pics of a th400 attched to the crossmember? Any suggestions on a little higher stall than what the car had stock? Do I need to mess with the speedo cable? Whats involved in that? Fill me in on the details. Im really in the dark right now with the swap.
