Better stick that heater control ahead of the glove box. I just took mine apart, and if you have the sliding controls you have to get your hand in there from the side to tighten the two upper screws. Mine were tight, I don't know if they are supposed to be tight or just touching. Hardest would be the defroster ducts to me, so I would start with them first. Just my uneducated opinion. On edit...mine is a 55-2 so probably not the same dash??
