Just a thought but if you can remove one of the rollers (looks removable?) you could take it to a local plastic supplier (most cities seem to have one or more). These are places where you can buy PVC sheet, plexiglass, etc. I've always found these guys very helpful in catering to my esoteric requests (e.g. parts for homemade saltwater aquariums and filters).
If they had something to measure the hardness (e.g. durometer hardness tester) then I'm sure they could recommend something similar. I have no idea what that might be as I haven't touched one of these but there are hundreds of possibilities from Teflon to Delrin and everything in between. Most materials come in bar stock and it would only take two small pieces to machine a replacement. With any luck you could get round bar stock of the same diameter which would make fabrication very easy.
Maybe it's a bit of an OTT solution but I bet the total cost would be less than $30 with machining if you shopped around.
And think what a money making opportunity you would have then with all these jiggling sun roofs!
