Been chasing a similar issue with vibes and angles. What angles did you end up with? I tried pinion down, pinion up. Trans is down 3 degrees, drive shaft up 1 degree to the rear. Front of pinion up to the floor 2.5 degrees. Vibe is better but not gone. Triagulated four bar. Sucks to move pinion angle, because I have to put it on alignment machine to get it square again. I have a 9" with a locker in it. I had a TKO in it, put a TKX in it to raise up the trans from 4 degrees down. Didn't think I needed to do tunnel work when I built the car. 2.5 to 3 degrees down I thought was stock. Had some noise from the TKO, still have some from TKX, might be from the rear I guess.
Thanks for the response.
