Really thankful for this thread. I used all the tips plus 911 manual in addition to specific instructions from J West Engineering that came with the kit and finished the job in much less time than I thought. Made a huge difference in my shifts as the ball cup was completely shot.
One thing that would be helpful was a video which I couldn't find so I filmed my own. Enjoy!
