i'm talking about the center of the steering wheel on my boat. it has a round, 2 1/8" opening, and looking inside you can see the bolts holding it to the "steering column". i'd like to find a replacement "cap" for this. would love to find an original if it had the grady logo or something on it, but a plain s.s. one would do. can't seem to find anything on the web, probably because i don't know what to call it. thanks-
