I have a 1980 Vanagon with a pop up camper top. Mine is the one that pops up
on all four corners as opposed to just popping up in front.

As I inspected some of the parts I noted that several of the neoprene
rollers are worn out. I have been unable to locate any of these parts online
(Busdepot, GoWesty, etc.) Does anyone know where I can locate parts for this
pop top?
