Working on painting the interior fiberglass panels and metal trim on my 1966 Mustang GT, Hipo, with a scheduled build date of August 12th in Detroit. The car has a deluxe pony interior with a Trim code of 64 which is Emberglo and Parchment. I am trying to match the correct shade of paint for the emberglo fiberglass panels and the metal trim that surrounds these pieces in the back seat. I found an article on the net which had a table of Mustang interior colors and paint codes for the 66 Mustang. The chart came from Larry Dobb's book "How to Restore Your Mustang". This color chart lists two emberglo colors for trim code 64 - 1) Medium Emberglo Ditzler 60485 and 2) Dark Emberglo Ditzler 50721. So, my question is to anyone on this forum who has restored a 66 with emberglow/parchment pony interior is there two different shades of emberglo used in the interior and if so, which items were painted medium emberglo and which were painted dark emberglo? The Ditzler paint numbers are old and my automotive paint store can not reference them. So, I am left using the existing parts and trying to get my paint store to mix up a close match. My interior parts are 50 plus years old so they are sun faded and it is not easy to see any significant shade differences. Can anyone help with any information on whether trim 64 should have two shades of emberglo used in the interior and which parts were lighter and which were darker. Thanks for any help.
