I'm familiar with the consoles but didn't know they had any sort of special coating. I thought the leather grain was on the metal itself so not of much help there.
I did want to point out that the interior paint colors are not the same as the outside. E.g. my car is Rangoon Red on the outside but the lower dash is a different red. I was able to use a Mustang paint for the dash, for the 64/65 Mustangs from Scott Drake I think, which shared the Galaxie colors that year.
