I ordered the pinion cup holder and it was on back order for several months...
the vendor recommended that I just get my money back and give up. The dang
thing was almost $200...
I made this thing out of a few boards...


The one board holds the flange, and the other board keeps the case from spinning...
there's nothing else left to turn but the nut in the pinion cup...
I have one final drive I can't the the nut off with my board-tool, or with an
impact...
I really like using the board-tool to put the nut back on, because I can use
a torque wrench and tighten the nut to the specified amount. The final drive
that I can't remove the nut from had the nut tightened with my buddy Dan's
impact wrench... "how tight does it need to be?" "Ida know - tight"...
