Let it begin

I'm back with a question , will my small brake set up from my 7 1/4 fit on the 8 3/4 housing with my sbp axles ? I will go to big bolt axles at some point but my budget just got hurt , my transmission went out on my truck while I was out of town and I can't wait to see what thats going to cost . The brake situation is not really important right now since the car is not going to be driven anytime soon just thinking out loud .
