Hello all. Years ago when scrounging parts for my RR I found an overall nice Bbody Dana but the mounts had been relocated. I didn’t have a problem with that. I bought some new mounts, located them side to side but merely estimated the angle in relation to the pinion. The car has been together for a while but suffered from some serious wheelhop with little effort. Trying out a couple softwares that total your angles and tell you where you have issues, I realized that rotating my diff angle 6* put the whole drive line in sync. I bought some 6* wedges and it worked but I do not like them in there. I had to but longer u-bolts and those size wedges actually lowered the rear.

So, on to the question. As a check before I remove the rear, cut off the mounts and weld on new ones at the new angle and refinish everything as nice as it looks now, does someone have the factory angle between the pinion and the mount?
