Well that is a whole different issue than I faced. I wanted to get rid of the 1 year only 65, cable shifted (front u-joint name is escaping me, Detroit joint?) obsolete front u-joint tranny. I built this car like it was going to be for me, upgraded the weaknesses (7 1/4 gone in favor of 8 3/4, dual master cyl etc. ) but I wanted to retain the stock appearance as much as possible.
