MY72BUG is a 1972 convertible. On both my original rear panels and my replacement ones there was no suggestion of an ashtray on either side. Not a big deal for me as I never developed the habit. I suspect that the shallow unit may be a factory original option as a deeper unit may interfere with the movement of the rear 1/4 window as it goes up and down. An excellent source of information for the convertibles is the site master of TYP15.com the web site for beetle convertibles in Krefeld, Germany. I needed to know some information about the actual size of the rear window glass for my convertible as I had glass and a frame which did not match. Michael Berger is the web master and he can pose questions to the ultimate information source, the VW Museum in Osnabruck where the convertbles were made in the Karmann factory. You can pose your question in English as Michael has made this web site multilingual. I am sure that he would be able to answer your question. Dan (ashtrayless) in Goderich
