Thats not what my 73 belts look like. Mine have a seperate belt that stows up in the plastic tray over the side windows. It has a retractor real on the outbard side next to the rocker and the buckle end is near the console. I believe 72 and earlier cars had no retractor so the long side was near the console and stowed in pockets on the sides of the console while the buckle was out by the rocker. I believe Firebirds always had the later style console and used the 73 Camaro seat belts. Also,I think the later 73 cars built after febuary of 73 had a cloth over cardboard headliner with the same type of plastic headliner trim that was used in the 74 and later cars and has a half year only special trim over the side glass that allowed for plastic trim to be used with the seat belt holder upper trays. But all my experiance is with base model 73 Camaros and Firebird Esprits,maybe the Type LT's are different.
