PPG Paint Help Needed - Poppy Red

Anyone know a good source for purchasing interior paint? A local paint supply company informed me that they do not have access to DMA336 in order to make the poppy red interior paint (PPG #9766LH). Looking for input from the forum, if you had success locating various paints that have been discontinued. With barn finds of old Mopars still popping up... someone must have a surplus of paint materials to make up Mopar colors.

I brought a interior piece to my local store and they scanned it If you are painting all the interior its much easier. Mine was light blue metallic and mixed in PPG as a single stage IIRC using DBC as the starting point. They were also able to get the formula in the achieves for the exterior EE1. I would try another paint supply store see if they can get you the formula.
