8.75 SBP brake options?

I have a '72 demon with small bolt pattern wheels on stock axles with stock style bearings. I already spend a bunch of money installing a small bolt scarebird front brake setup (like it!)along with wheel vintiques 15"x8" and new 275/60 BFG tires, so I don't want to go big bolt pattern now.

I currently have the narrow a-body 10" drums on the rear-the ones with the 'skirts'. New drums are getting pretty scarce, so I would like to switch to a different brake setup. I am not afraid of piecing stuff together or re-drilling the small bolt pattern onto different rotors, but I also don't have a problem going with a different drum setup if it doesn't hit the backing plate.

Oh yeah- I need it to be cheap!!

Some ideas I'm wondering about:
-small bolt 7.25" drums and backing plates
- do they swap right over or close on the 8.75"?

-jeep/ford stuff with custom brackets and redrilled rotors
-I know the wheel will go outboard the thickness of the rotor

Thanks!
