Quote: If cost is issue the nice thing about the 8 3/4 to Dana swap is parts. If you make the Dana 1" narrower than the current 8 3/4 the current ends can be cut off and reused, along with the axles and brakes. The stock gears will take a ton of abuse. Buy a used Dana that features a 4.10, cut it up and add spool, done. Doug
You can put mopar ends on a nine inch and use your existing brakes and axles too.
The 9" obiviously enjoys huge aftermarket support. True those components would work, but would you use a factory 9" carrier? I'd bet not. How about using a stock unbraced 9" housing? I'm not up on the quality of the factory 9" gears. They may be usable? My point is the Dana is very stout in stock form and cheap. Doug
