At a recent event, I had a deduction under Coupler(rag joint) assembly, it said missing black plastic insulators. I went to my trusty Long Island Corvette catalogue and ordered a pair of coupler pin bumpers. I assummed that was what I was missing. Well, when I got them in the mail, I already had installed those pin bumpers a couple of years ago. What in the world am I missing then??? I'm puzzled.
