From my review, 1968 Camaros used a peaked style TRICO brushed stainless wiper blade stamped MADE IN USA (Photos 1 & 2). As best I can determine this peaked design carried through into the 1969 production year however at some point Chevrolet switched to a bevelled design (Photos 3 & 4). Does anyone have information on when the bevelled design came into assembly line use?
