hello everyone, my name is tad franklin and im new to the forum. i have a question about a mustang i recently purchased. it was sold as a 66 hcs. the dso # begins with 51 (510230) to be exact. it has a blank color code, hcs badges, a yellow paint (aspen gold???) under a light yellow paint, from san jose plant, and sold in denver, co. however, the build date code is one month early as compared to what the rest of the 333 were supposedly to been dated. mine is june (sold in july at courtesy motors), others have been listed as july. ive heard dealers could get some early, is this true? could mine be a demo? or early production? also i realize all of fords records from 66 back have been destroyed. is it a fact to assume all 66 hcs had the same build date or is this info derived from numerous articles over the years? anymore info on this topic or related topics would be greatly appreciated and extremely helpful....also, i am having trouble locating a dupont or ppg paint code for aspen gold. does anyone know what the paintcode might be or where i could find it. thanks. tad.
