74 spindles and 11.75 rotors

I just cut the gasket out of thin white packing material. Check www.rockauto.com for bearings or info. Usually I just read the PN, like Timken ___ on the bearing and race. You can find most bearings that way, even unusual ones. You can also measure ID, OD, and thickness. I understand all standard bearings have always been in mm, going back to Germany.
