10" rear drum brake parts

I am swapping out the old SBP axles in my 8.75 but sticking with drum rear brakes.
I found a somewhat local guy that has a pair of 10" BBP backing plates for me. I want to buy all new parts for a complete set of drum brakes.
What year car would i search for to find 10" brake parts? I will be buying new axles from Dr. Diff i would assume since they have them in stock.
Not sure if i should buy the complete rebuild from them also, except drums?
The complete kit is not in stock right now, that was my original plan.
Shipping is crazy expensive, that's why i was hoping to buy local if possible.
Any info would be greatly appreciated.

Thanks!
