Thanks guys.

I think I found my vibration problem. The tail shaft sits at 5 degree down, the driveshaft is 4 degree down and the rear diff is 5 degree down.

Both ends match, but the problem is the rear pinion is higher than the drive shaft and everything I read says that will cause problems.

I ordered 2.5 degree axle shims to fix the rear and then I will see if I can shim the transmission up 2 degree.

I figured that since I used dodge engine mounts and tranny mounts that I would not have a drive line issue, but I also swapped in a 904 instead of the 727 which is shorter and I replaced the rear springs. All of these accounted for the angle issues.
