There are Windsor distributor gears available in the same 0.531" shaft diameter as the Cleveland distributor gears. How they differ I can't say, I've never compared the two.
If you were breaking in a new flat tappet camshaft with no ZDDP in the oil, you should pull the cam & lifters for inspection too. Make sure to mark which lifter bore the lifters come out of, because if you re-use them, they must go back into the same exact lifter bore.
