No I would bet my life that it is the pinion angle. The Rear has been replaced, Transmission rebuilt, Been taken out a few times and since then major vibration. I have been reading some interesting article with the proper way of setting that up by measuring from the Transmission tail shaft... I bet it was never done correctly. Geometry of the drivetrain is huge. Robs you of power, time... We need to speak to someone that really understands all this to help out. I'm sure I'll find someone up by me.
