You can't use the auto's transfer with the 5-speed.I thought my auto and tranfer were one piece? I got a whole W56 tranny and transfer for mine. once i drilled the holes in the firewall for the master everything was a direct swap.It'll be a BIG difference to drive, lots more power. <img src="/forums/images/graemlins/kewl.gif" alt="" />
