RV awning parts?
 

I have an old Winnebago with an awning. The end cap of the awning, plastic, is busted and the internal spring is now sticking out. I have been searching high and low for a replacement part, but can't seem to find it online. I found a picture with the part in it, but the part I need is not listed. ANyone have any sources or thoughts on where I can find the part? It is the gray round cap, sort of in the middle of this picture. The only difference in mine is that it has small knobs on it.

Nevermind, found what I was looking for. :bo:
