Marty, the Camaro's I have found with broadcast sheets showing the special paint used Dupont formula #96881 which is now referred to as Wedgewood Blue National Fleet color. The mix formula was actually first used in 1964 in the BOP lines under various names: Wedgewood Blue (Buick), Bermuda Blue (Olds), and Skyline Blue (Pontiac). It has been many years since I originally researched this, but I am pretty sure when we scanned the sides of the cowl and a couple areas under the cowl panel this car used the #96881 formula. The other mix formula that shows up in 1970 on some Chevelles is 926-98371 which is what I believe is on Charley's buildsheet for his Chevelle. I have never come across a documented car that mentions paint code 80 or the Dupont formula number or 5022L/D on the paperwork, and that color actually has a purple tint to it. I will have to check tomorrow, but I need to cross-reference the 5022L again to see what the 5-digit formula number is from Dupont. From what I have found is that both the #96881 & #98731 were both used through the 80's as fleet colors off and on. There was supposedly a buildsheet found in a 69 Nova that had a Dupont number of 4531L printed on it, which is exactly the same as the #96881, but I have personally never seen it. When looking at a buildsheet/body broadcast sheet, the GM order number for non-metallic special paint should start off with 926, and if it is a metallic it will start off with 927. I have a buildsheet for a 70 Chevelle with special paint and it reads: - - PAINT DEPT 1001HA: HOOD, FENDERS, AND ENTIRE BODY - 926-99616 ORANGE ACRYLIC LACQUER. This car is an LS6 out of the Arlington plant sold new in Broken Arrow OK. I hope this helps................RatPack......................
