I'm not sure of the code number without looking at the car but I have a 66 convertible parts car that originally was Sahara Beige with the the parchment/emberglow interior. As far as the books go, this combination was not suppossed to be available. I believe this must of been a special order.
This is a pic of the F4 code Pony Int. (parchment/emberglo). In combination with the Antique Bronze ext. colour, it was no standard. It is indeed a special order and export car. I was just trying to figure out, if this is a unique combo. Impossible of course, I know.
