New to restoration though I have had 2 mustangs, 66 coupe 289 and 1999 coupe. Now have a 69 mach 1. Need to know if there is a trap door or divider between the rear seat and the trunk. Mine doesn't have a rear fold down seat. Not sure if it ever did. I understand that was a factory option. I have seen dividers for coupes and convertibles but nothing for the fastback.Thanksjrw69
