angle issues,today set it at,trans is 2 deg.down towards the rear,so i set the pinion at 1 deg. down.allowing for 3 deg rise from the pinion.the vibes before were so bad it would knock the rear view mirror down at 70 mph.today i have no vibes at 50,60,70, but at 80 they are noticeable,i ran it up to 90 and at least the mirror didnt fall.i think im close on the angle.but at 90 they get bad.any ideas? it has to still be the angle,because it got so much better with the change today.
