Added a 1 deg shim to the axle bringing the pinion up. Seemed to help, vibration less sever and at a little higher speed.
Added another 1 deg to the mix, vibration at a little higher speed again but still their. Now I am getting quiet a bit of vibration on hard accel also. So while moving it up seems to help at speed it is making it worse under acell.
Right now the tranny is 3.7 down, rear end is 2.5 up and the drive shaft is .5 deg going up toward the rear end.
