Phil, were you ever able to get in touch with Dennis? I was down there about a week and a half ago and he's got even more parts cars down there now. Quite a few '66/'67 A-bodies that probably have decent inner fenders.

Know what you mean about your son...Mine went through that a few years ago, He was just a teenager but it really tore him up for a while. Best cure for woman blues is a new one...unfortunately.
