Chain rings -- 8 vs 9 speed

[rek]

Hi guys, quick question ... I've found a good price on some Blackspire road chain rings that are marked as "8 speed"..

Will these be compatible with my 9 speed Shimano setup, or might there be differences (I'm guessing either through tooth width or ramping/pinning) that would screw things up?

There might be some slight differences,that would bother the ARs. Nothing will screw up.
