Thats a tough question to answer, but from what i know, they were never used on Motion cars until 1970. A few 69 cars have had them, but that seems to be because they were not actually SOLD until 70, so it makes it "acceptable" for these cars to have them. I have seen several different variations of original ones, Chrome plated, polished, large Motion emblems that were modified to fit into the recesses of the covers, and smaller Motion emblems that fit without modification. Motion also sold these covers through their own speed catalogs, which they published each year, and actually made them for big and small block, and even Ford and Mopar too! I'd have to say they "never" really stopped selling them, as i believe even til this day if you have a real Motion car you can buy them from Joel.
