I'm going through the same thing with my red interior chevelle. The upper is the zero gloss suede paint as Jeff mentioned. On my 66 chevelle there were two different interior colors used. The upper is a darker red suede zero degree that matches the dash pad. The lower dash, console, tops of the doors, seats etc were a medium red semi gloss. You can contact Jimmy Chips atTCP global and he will be able to look up the correct Ditzler or Dupont paint codes you would need if you are trying to put your interior back to the correct factory color. He worked at Ditzler back in the 70's when they supplied the paints to GM. He is a very knowledgeable, friendly guy that loves the old car hobby. I have his number and direct extension if you want it.
