I would like to add air to my non-air 67 Firebird. I would like to buy a complete system. The only system I can find is from Vintage Air that sells for about $1150 locally. I would like to know are there any others? Even an underdash unit would work for me as long as it looked nice and would fit without any modifications that could not be easily fixed if removed. If there are no others can a vintage unit be bought for less?
