The car pictured in the link is one I cleaned up for a friend a number of years ago. I matched the blue to what was on it, however, I think it was Sears "rebuild blue" - the color they painted most all of the short blocks they sold thru stores and the catalog. The pictured car had 12K original miles and was essentially original. The engine had a cracked piston which I replaced. The owner still has the car and drives it from time to time.
I have more pictures if needed.
