Between 52 and 65 or so. These are the things I've changed or checked

run out on axles .004
brake drums replaced
wheels tires switched with known
rear axle bearings replaced
shocks replaced
u joints replaced
balanced driveshaft

trans angle -1.8
driveline +1.6
pinion +2.0

I read it needs a minimum 1.0. Is this my vibration?
