I got the kit from CCP, around $300. You'll know when you get the end play right. I had too much and had to play with the different thickness spacers until it was good. Watch that you don't mess up the shaft seal if you have to take the cover on and off.
The detent ball/spring and plug need to be removed before the cover is removed. It's right by the shift fork. Count the number of turns on the plug coming out, and don't lose the pieces inside.
Good luck with the project.
