I've been searching and can't find it, but does anyone know the center bore size for some adr sterling 18" wheels...

The part number is ADR7885851435ms

for some reason, it isn't listed on the box with all the specifications.. lame

I really don't wanna take the wheel off and measure it.

have been to adr's website and it isn't on their website either.

I'm figuring it's probably the standard 73mm, but i wanna make sure before i order the hub ring and shiz.
