Driveshaft angles, here we go

[dickdale]

I've got a vibration at 60-70 mph. Slighty noticable a 50 mph.

My trans is 2,3 degree down and the pinion is 2,5 degree down. I'm using Hotchkis leaf springs and shims already. Which angle of the pinion is acceptable?

I'm really tilting towards doing a QA1 tubular swap this winter and get rid of all the crap.
