will the sprocket carrier on a cb750 sohc disc rear brake fit a drum rear brake? the reason i ask is i am trying to locate a drum rear wheel hub or complete rear wheel, without any success, so it looks like ebay, problem is nobody wants to sell a complete wheel, its a wheel, a brake plate, and a sprocket carrier, i have a carrier off my disc brake, so do i need to buy all three parts or will i get away with two.
