Very cool 1972Dusteragtop - thanks for sharing. Yes the slide back soft top A bodies are few and far between. You are correct - the "sunroof" option was not coded on the fender tag directly - but since there were no A body convertibles for 1971 and 1972, they coded the roof as V3W or V3X - which is the same codes for convertible tops on E bodies. Being a 1972 and earlier factory sunroof car also - you should also have a special Vehicle Order Number (VON) on your fender tag. Thanks,
