[392cobra]

Roger,
Maybe I am reading your post wrong judging from blykins reply.

Going front the front to the back of your Cobra;the trans angle is down and the driveshaft is up ? If so I would suspect your pinion then goes down ?

If so you are running positive which is not good.
I would head down to Sears and get a magnetic protractor,about $10.

What I now have is:

front u-joint operating angle - 1 degree

rear " " " - 1 degree

pinion angle neg. 1 degree



engine slopes down 1.5 degrees

driveshaft slopes down 2.5 degrees

pinion shaft slopes up 1.5 degrees (equal but opposite and parallel)
