I have herd that Mcmaster carr makes/sells twin and triple replacements, can anyone confirm or deny these allegations?

Absolutely not. They have a website, with an easy to use search function. Try it sometime.

thanks, Douche, I have a friend who had the mcmaster book and he use to order disks from them for about $25.00 per disk a couple years ago, I'm fairly sure they were not for an automobile but for a some heavy equipment. But thanks for the help!
