Since all these threads always spin out of control, like a winter time valve lash discussion, why not just....?

Put the drive shaft in it, slap the angle finder on the shaft, and check it against the pinion. It's a door car that you're not going to change the driveline angles in, so knock that off the worry list. It needs pinion to bite.

Put three in it, hit it, and see. The object is to get to the track right? I've been as high as 10 degrees on a ladder bar before.
