yes, the 9" and 10" are both interchangeable on the 28spline 8.8's or 7.5's. but why downgrade? Most want to put 10" drums on their 9" stock trucks.

well to tell u the truth when i had the 7.5 with 9" brakes when i put all new shoes and hardware and wheel cyclinders and all new everything i think that they stoped the truck just fine even with the 33"s.. and i cant get the 10" to stop locking up under heaving stoping conditions for the life of me... but thanks for you imput ill be switching back to the 9":icon_thumby:

I did the same thing when i swapped axles, the 9 inch brakes will drag the rear tires no problem. I actually have trouble locking up the front wheels but it still stops great.
