300zx 26 mm aluminum caliper help!

Hi, I lost the o-rings that go between the two halves of the calipers. I heard somewhere that you can just get them from a hardware store. Does anyone know what the dimensions of them are?

I remember someone said he got it from Ace hardware store. I think you should take the caliper with you and try some to find out the best one. You are not supposed to take them apart, so Nissan doesn't sell that o-ring.

oh ok. Lame! I was wondering why the rebuild kit didn't come with them. Does anyone know what the outer diameter is? That seems to be the only measurement that kind of matters. Thanks for any help!
