    IMO it is easer to convert from man. to auto than the other way around. There might even be some people willing to do swap parts w/ you (including me if you live in SoCal) [​IMG]
    You would need a trans, xfer case w/ adapter, shift column, driveshafts lengthend/shortened.

    Would the crossmember have to be changed also? Also do you need to swap transfercases?

    Yes, you need to change transfer cases. Manual trans xfer case uses a 10 spline input and a th350 uses a 27 spline. You could just swap the shafts but you have to take the whole thing apart to do it.
    I don't think you have to swap the crossmember just move it back.
