Flywheel 122 Tooth

Is that a standard 10" clutch or will it work on the 9.5" flywheel. (scalloped pressure plate). Brewer used to sell those for stock applications.
it works with the 9.5" wheel, the PP is scalloped enough and the disc isn't technically 10"

i just bolted one together last week, so it's pretty fresh in my mind. i'll double check the PN on the box though.
