...Also in checking driveline angles, the pinion is 3* up, the trans tailshaft is down 3*, the driveshaft was nearly in line with the pinion.
I know there needs to be a few degrees of driveshaft angle to lube the u-joints but do you think the way this sits it would cause vibration?



Yes, I've heard it will cause a vibration and excessive wear, but it may not be the sole source of your vibration. The u-joints need to have some movement as the driveline rotates. You can use shims to nose down the rear 3 or 4 degrees.
