Here's the report guys. Vibration between 25-35 mph is pretty bad, it resonates through the entire vehicle. I'm not sure if its the pinion angle or the stick-out of the T-case yoke or both. I'm pretty sure I'm going to have to cut off the perches and weld a new pair on to fix the vibration. Since the pinion joint is so strange I'm having a hard time finding information about it. Take a look at the pics and tell me what you think. Other than that it was a successful project. Will take some articulation pics tomorrow, I have to measure for my new shock anyway.
