Firebird standard and deluxe rear seats are all the same. Coupe and convertible are also the same, as is fold down (size wise). Now the interesting thing is that 'Maro rear seat for deluxe is the same as firebird, but 'Maro standard rear seat is 4" narrower. Me thinks they used the wrong pattern, or you somehow ended up with standard size 'Maro covers. Does your 'bird have standard or deluxe interior?
