SYE and now 8* shims?

Another thought that came to me is that the driveshaft didn't vibrate when it was in the front, but has a slight one now. Could be that the u-joints are still the ones from the front? They're operating in different phases now and that can cause vibes too.

I concur on the thought that an anglefinder is needed, because that pinion *looks* too high from the pics.
