Exactly, plus it was a 3 bolt instead of a 1 bolt sprocket.
I said it was different but not in what way. So there you go.

I had forgotten about that, but that's correct, too. Thanks. I'm not sure doing the low taper thing actually helped, but the entire A12 package was hard to deny. Those cars hauled butt. So, maybe it contributed something. Who knows?
