93s have different locations for the AIR fittings on the pass side. The 93's have the AIR fitting near the #8 cylinder and no ERG tube connection.
94-95 headers have the AIR fitting at the #2 cylinder and an EGR fitting back behind the #8 cylinder.
96-97 will have the same AIR and EGR fittings, but since they are dual cat Y-piped the drivers side has a shorter distance to where it would bolt to the Y-pipe.
