So, I'm trying to sell a set of cams for a buddy, but I don't feel comfortable getting rid of them until I know exactly what they are. I know that their part numbers start with 253-. I called Crane, and they said the number on the cams are simply the # of the blank. It's 253-9566 and 253-9567. Is there any other place I can find cam info? There's another nuber on them after that number. 0231A. Anyone have any idea?
