Does anyone know of a good supplier of wiper blade replacement elements for older cars (1966 Starchief)? The type that slide in with a little metal retaining clip on the end. The only replacement wipers I can find are on replaceable frames, but the frames on my car aren't replaceable. The last time I replaced wipers I bought a pair with the frames, removed the elements, threw the frames in the trash, and installed the elements on my wipers. They are now worn out, and I can no longer find replacement frames with removable wiper elements. The size is 17" long, and 11/32" wide..
