I didn't have that issue with my Marks and I guess I don't really understand why you did. Was it because the angle of the tranny changed when you mated it to the V8?
Yep. We angled it a bit to get it lined up the way we wanted it. Just enough that I had to have a 1/2" taken off the drive shaft. Nothing major, like I said, I didn't even notice it till about 6 months later.
