I've got a bunch of rotors, at least 10, and need to get rid of them. These were bought new from a local dealer a few years back for vehicle testing and we never used them. I believe we paid over $100/ea., but would like to get $25/each plus shipping. I've opened a few boxes to check the condition and for the most part they're good but with slight surface rust from sitting in the garage for so long with humidity and stuff. It's barely noticeable and pretty much around the edges. I think these fit early 2000's 1500 2wd and 4wd Dodge Ram Pickup with the the rear disc brakes. There are two sets of numbers stamped around the outer edge: 974550 and 137070.
