The heater box is missing on my'74.......there IS one on the 'glass tub,but the motor sticks out thru the fire wall.The tub appears to be pre-'76 style(flat floors)but is was preiviously installed on a later chassis,&had the later style dash,seat brackets,&a firebird tilt column on it.I'm gonna put the early style dash&column in it&keep that heater.
