Just got my 1976 El Dorado convertible in Commodore blue with the light blue interior which I believe Cadillac called antique blue ...I purchased a dash overlay for it as a temporary measure because I can't afford to have the dash completely redone at this point..Whilst trying to match the paint for the overlay, and it was near impossible Luckily, a friend of mine at work helped me track down the paint code numbers and I was able to find an exact match for the antique blue dash color. It's a dupli-color brand called medium blue.... I never thought I would find it. I was having custom paint mixed and everything and no luck. Nobody could match it and all....the whole time Dupli-color already had it and a spray can.!!! I'm extracting at this point..... i'll publish some more pictures once I have it painted.
