This is all I could find. It's a copy from a Winged Warriors newsletter that was taken out of the 69 sales interior/exterior trim guide. I have seen this in an original guide. It's a small blue cloth binder. There is an asterisk next to the word in the lower table column marked "Carpets*"
Below the table it explains "Black carpet only with 4 speed manual transmission". There is a clarification somewhere else that allows colored carpets when you have a 4 speed with console. Again, I am not being critical but with your concern about perfect hubcaps, I thought you'd want to know. Maybe they made an exception for green interiors? They should have? I had an F8 green 69 Hemi Bee with the two tone green bench seat but do not remember the carpet. It's owned by Joe S. in NY and was restored by Kohrs out of PA. I think it had a black carpet?
