I am replacing all of my Rub Rail and that includes the Rubber insert, I have 50+ feet of the old insert, (its not in bad shape) and I will probably have some left of the new stuff when I'm done replacing mine. Does this help you? Let me know, like I said the old insert I took out is in good shape, the only reason I'm replacing it is becasue the PVC Rail that holds it is an Eyesore.
