To answer some questions:
The transmission is setting ~ 1/2" shifted to the right. That is 12" from driver side frame and 11-1/16" from passenger side frame.
The pinion is setting ~ 3/32" shifted to the right. It's 11-9/16" from driver side frame and 11-3/8" from passenger side frame.
Right now I have the upper links off, the bottom links on blocks, and the pinion setting on a bottle jack, to adjust pinion angle. Oh yea the springs are off too. It is a triangulated 4 link, with the top links angling out to hold it centered. I would guess the pinion was intended to be centered and it may well be when the upper links are on.
Drive shaft is 11" so the off set gives a 2-3* side ways angle.
I couldn't get a good reading off the harmonic damper with the pulleys on. The pulleys are not machined perfect. I get anywhere from 0.8* to 1.2*. I tried the bell housing,
oil pan, and others with no better results. The throttle body top gives a solid repeatable 1.1*. Everything else it near 1*, so I'm willing to call it 1*. Close enough.
I blocked it to equal a ride height of 5-5/8" frame above floor. The lower links start to angle and pulls the assembly forward. Then there is no free play left in the transmission yoke splines. The angle on the U-joints is much more reasonable here, but since I couldn't pull the drive shaft out to get a reading in the pinion yoke. I quit. Crawling in and out from under the car. Then jacking and blocking is a royal pain.
Ok, this is going to be much more involved than I thought. I am building adjustable upper links this week end at a friends shop. I will work some more on it then. It's looking like a may have to have adjustable lower links too.
