Thanks for the info! So I should be able to use the backing plates and brake set up from the current 7 1/4 rear axel thats in the car currently

No, probably not as they are likely 9”. If they are 10 they’d only be 10 x 1.75” at best but 10” is unlikely on that diff.

if you don’t want to chase junkyard parts, call dr. Diff as he can sell you everything you need brand new...
