Found this part in my storage. I have had it for most likely over 35 years. The part number molded into the rubber part is C7WB-16B554-B. The mystery is the “B”. I believe the “B” indicates it is a revisioned part number but can’t be sure. I can find no other record of the part number existing anywhere. Maybe one of you sleuths and part number experts know what the story may be. Have fun, let us know what you find out.
No, C7WB-16B554-B.
Can you post a picture?
