Hey guys I'm building a 76 cb750 from scratch. I want to use the black com star rims that were used on the 80's versions but the hub is different. On one side there is the sprocket and on the other is a rotor. Is there a way to swap the hub out for one that fits on the 76. I see many 76 builds with the black com star rims. This is my first build and any information would be much appreciated!
