Hi Dan, Thanks for looking. Your correct there weren't any 77 convertibles produced. I've never seen one before or since, so it's as far as I know a One Of A Kind. As the story goes, told to me by the person I purchased it from. A gentleman purchased the car for his wife, new. The car supposedly went from the dealer to the coachbuilder for the conversion. I'm currently trying to research this, haven't had any luck yet though. If anyone might know who would have done a conversion like this for GM around 1977 It would be greatly appreciated. The car has a stock 403hp in it with enough pep when needed, but I'm not really a speed guy, I'm more of slow cruisin' guy. Other than that it's a stock Cutlass. Right now I'm working on converting the interior to buckets, but the seats are hard to come by in good condition at a reasonalbe price. I'd really like to do something about the top, because I really don't like the way it looks with the top up. Whem I get a chance I'm going to post more photos. NICK
