I can't find any pics of the 9999 interior'd 'Cuda, but ran across a note about a FC7 '70 383 R/T SE Challenger (205372) with a 9999 interior code. Wonder if it's a bench seat R/T that I keep hearing about , but have seen NO proof.

IIRC there a '66 Newport convertible with a 999 interior code & it has a New Yorker ONLY green leather interior in it.
