setting of my pinion

My tranny points down 3.3 degrees and the driveshaft is up 4.3 degrees and the pinion is down 2.8 degrees as I measure on the snubber location. Does this seem correct? I feel like I have a vibration on acceleration. What should I do?
This is a 904 with a gearvendors, 8 3/4 rear in a 72 dart.
