Drive line vibration updates

Ok so to any of you who have been following and mostly helping with my vibration issues, here's where I am. I have tried different pinion angles with no success, I have tried 2 driveshafts and had both balanced still no change. Bigsuger had a topic on his similar issue and I remembered one of the replies to his was that not only is pinion angle important but driveline alignment is as equally important. So today I put the car on the hoist and pulled the driveshaft again. I ran a string line along the motor and trans centerline then checked it with the diff and voila!!! The pinion was pointing to the passenger side? After more investigating I found the passenger side rear leaf front mount had been hit and is pushed to the rear almost 1/4"   I'm not really happy about this but I believe it is the root to this !  So I guess I need to get the mount pulled straight. While I had the shaft out I took it back to the shop to recheck the balance. This time they said the yoke u joint was too loose to be serviceable  :brickwall: so now they are building me a new shaft but to their good enough to discount off what I had already spent. So I'm ok with that.

Ill keep ya posted on any improvements I find

By the way the car won a 3rd place for the 70-79 North American category and 1st place overall for mopars last weekend I was pleased.
