I noticed all these cars were 1970's, do you have Dealer codes on 67s and 68s since in the earlier years ,there wasn't as many dearlerships . Do you know when these dealerships received their dealer codes,codes might not be in sequence as they added new dealerships throughout the USA in later years.Take note ,Courtesy Chevrolet Phoenix Az. 087 It's been there forever. Anyway I have what I need and doc's to prove. Thanks Dan
