[78w72]

ACC, although some have reported fitment issue recently, my ACC 2 piece fit great in a 72 firebird and the 1 piece in a 78.

Best price for these carpets & many other items for these cars is from larger companies like Summit, jegs or Rock Auto etc, vs the smaller ones, they all sell the same parts and larger companies will usually be quite a bit cheaper than the smaller companies like classic or the central or warehouse or graveyard places.
