I have two new rotors in my collection of parts that I don't know what they fit. There is a part number 16-00508 511-240 on the boxes. They are about 10 5/8" in diameter. The "top" is 5 7/8" in diameter and 1.5" high. My part number searches have turned up nothing. Seems like I tried them on my 240 years ago, but they weren't correct. Assuming I picked them up in a parts lot from someone. You guys have any ideas on how to determine what they go to? Thanks in advance
PS. I hope this is the right place to bring this up. Haven't visited this site for a long time.
