I bought 2 aluminum racing flywheels for RX-7, one new and One used.   Both were same diameter as 2nd gen flex plate although the seller said they also fit RX-8.  

I am not familiar with the " FB or FC " terminology.   I'm wondering if they mean it is a 1st gen RX7.   I would assume FC means 2nd gen since 3rd gen is FD.

Well, I recently bought a used aluminum flywheel with the following description:

Quote:
RX7 8.5Lb Fidanza Aluminum Flywheel for FB or FC
For sale is a 8.5lb Aluminum Fidanza Flywheel for a RX7 Non Turbo , its used and could use a new friction plate
fits 86-91 Non turbo RX7s might fit Fb 2nd gen RX7s as well i'm not 100% sure
Unquote.

It was reasonably priced, since I don't need the wear surface, so I figured it would be 'plan B' if I ever have an issue with the flex plate.

When it arrived (yesterday, after everyone was gone), I sat it on top of my (cracked) flex plate, and it's almost an inch smaller in diameter. The mounting holes in the center seem to line up properly. I remember reading about milling the drive plate to move the starter .2" closer to the engine, but I don't remember anything about the smaller diameter.

So, my questions:
Did I purchase the wrong item, would I simply make my starter cutout in the plate closer to the centerline to account for the smaller diameter, or was the flywheel mis-represented?

If it's not the described item, I need to send it back, but I don't want to bother the seller if I simply bought the wrong flywheel.

Thanks,

Charlie
