Do you think this pinion angle will be alright for street use? Or should I possibly shim the rear axle up to bring the angle down.

Your u-joint angles should be 0.5 - 3.0 degrees and right now you are at 3.4 degrees on both u-joints. A 1.0 degree shim should put you back into spec on both u-joints.

That is about what I had in mind. Would like to get the rear pinion down 1-2 degrees from 5.7. Thanks

Sorry, I don't think I stated that right. You need to adjust both angles. If you can get the transfer case to 4.7 and the pinion to 4.7, you should be golden
