Replacement for Wilbar 11456 Top Cap

I realize this has been asked a couple of times before but I’ve yet to see that anyone has found a solution. Has anyone found a suitable/workable replacement for Wilbar part #11456? I know that the original part has been discontinued so now I looking for alternatives.

Ideas? Anyone??


At this point, Wilbar does not have another option for replacing the 11456 top cap.
