I have a set of old Anco wiper blades that I would like to reuse if I can find the rubber refills, but am coming up short. All I can find are the newer style that are made of plastic. Does anyone know if these are even still made? I know these might not be as good as the newer style, and I'll go that route if I have to, but I like the odd-ball stuff and would like to stick with these.
