I'm looking at a 130 tooth wheel and I see them listed for both. What's the difference?? Is it the bolt pattern for the crank?

In 70 or 71 they went to a scalloped clutch...10.95" disc and hat that bolted to a 10.5" flywheel pattern, so then the BB and SB could use the same flywheels...aside from the aforementioned external balance issues that were specific from engine to engine. 2 Demons...no, not my kids!
