quick reply:shims

89xj, 4.0, 5speed,sye, c-8.25

My ds angle is 0* pinion is pointing directly at the output and causing vibes.I have a 4* shim in there now should I leave the shim out altogether or put in a set of 2* shims I have sitting around?
My fear is by going with no shim at all that my pinion will be too low.....what do ya think???

2* - 3* is what you need.

What's your pinion angle? Get the pinion about 2 or 3 degrees down from the drive shaft. When you accelerate, the pinion rises a little.

should have stuck the 2* shims in......I put it back together without any shims and the pinion is a little low.....thanks for the replies.
