7 1/4 to 8 3/4 rear end interchangeable parts

I am going to put a A body 8 3/4 rear end in my 66 Barracuda and was wondering if since the 7 1/4 has 10" brakes and the 8 3/4 has 10" brakes and everything in the 7 1/4 is new, will the brake shoes and all the hardware fit on the 8 3/4, and also can I use the park brake cables from the 7 1/4 on the 8 3/4? No sense in buying everything new again if I can just swap everything from my 7 1/4 over to the 8 3/4. If anyone knows please chime in.
Thanks
Bob
