I installed mine and realized that I was not able to adjust it while it was in the gearbox.
To remedy this problem, I removed the diff, used a cut-off wheel and made a slot in the diff screw.
This way, I can use a small flat head screw driver and tighten or loosen the diff with it in the gearbox.
Just make sure to install the out-drive cup with the pin on the same side. You will have to remove the out-drive cup in order to tighten the diff.
Hope this helps.
