273 Commando Air Cleaners and Valve Covers

My Barracuda was originally a 273 2 bbl car. I put on a factory 4 barrel intake and small carter afb. I found an factory air cleaner and base somewhere (it was the 80's; it was easier then). The four bbl and 2 bbl air filters are the same diameter for that year. The 2 bbl is slightly shorter if you are looking for extra hood clearance. Since you are considering a thermoquad, I have no idea if this info is helpful to you at all.
