A body 8.75" housing

I have the opportunity to buy a bare A body 8.75" housing. Can I use brakes from an 8.75" equipped C body if i get custom axles? How much wider would this be than using the stock A body brakes?

I recently bought a 65 V8 Dart parts car with a 273 and 7.75" rear end. The brake drums are bigger than my /6 wagon's 7.75" rear end had and are bell shaped like the A body 8.75" rear end brakes - can I fit these to the 8.75" housing?
