Hi Dick, You are very correct on the '65/'66 difference. The Skylark and the GS shared the same covers. The plain steel wheels only differed in the width. The GS used 6" wheels, same as the wagon. The Skylark used 5.5" wheels. The rally wheels were an option and that can open a whole new can of worms, as there were changes in those through the production. Loren

Thank you for posting the pic. That appears to be the standard cover for a Special model. A Skylark standard wheel cover is not the same. I've included a copy of page 79 from a dealers "1965 Buick Features and Facts" book. The correct standard cover for a Skylark is located on the top row in the far right corner. Regards, Loren

Hi Dick, PM sent Loren

Do you have some pictures available? Thanks, Loren

Do you have a picture of the passenger side valve cover?
