That looks like a totally stock set up to me. All I am saying is spend less $$ to build a 9" Correctly instead of spending more $$ on an 8 3/4 to keep doing it over again. Good $$ spent once, Done!
Thats a 3rd bearing failure, that can happen on any style 9", but when it happens its costs you the case, shaft and trans, something any Dana or 12 bolt, 8.75, 8.8, 10 blt won't do when / if they break, it's a simple R&P.
