There are two depths for Berlinas. The 72-73 cars with 14-gal tank, threaded gas cap, and "hump" in the top left of the tank are a couple inches deeper, and need a correspondingly longer float arm. 74 cars with 12-gal tank and bayonet cap have the shorter style. The longer style are not available new as far as I know. I got one a couple years ago from Centerline when they had a stash, but put it in a friend's car.
