In 1951 KF began using Garden Green metallic as their engine color. That same color became Olive Green metallic and was used by Chrysler Corp on their interior painted surfaces in the late 1960s. I own a 1970 Dodge Coronet and its interior painted surfaces are a match for the KF engine color. A formula is available from Sherwin Williams Automotive Finishes in the Dimension product line. I had a pint mixed and used it to paint the block on my Darrin. It has held up with no fading or peeling.
