Different FC pulleys?

[need RX7]

I bought a new main pulley for my S4, since mine was really rusty and the timing marks weren't visible. I ordered one from eBay that was supposedly off of an '86. I got it and compared it to my old one, the timing marks match up perfectly but the overall diameter is larger. When it is installed on the car the outer edge scrapes on the timing pointer. Did Mazda change the pulleys from S4 to S5? The one I had before is ~4 1/2" and the new one is ~4 3/4".

The S5 main pulley is larger than the S4..

:o10: Thanks. Looks like I'm gonna have to hit the old one with the wire wheel.

Another question kind of stemming from the original question; are the eccentric shaft hubs the same between S4 and S5? I have an extra one that came with the pulley I bought that I'm looking to resell.
