CA 1963 Delux heater complete whole setup

[Inkfamous-13]

I've got a 63 Deluxe heater that I purchased from a guy that was putting a new heating and air system in his truck I was thinking I could convert it over and use it on the 66 cuz I've seen that done before but forgot that mine has Factory air and it doesn't have that diverter piece inside of a has nice controls the cables everything's there but the heat thermal switch I believe it's called not sure it's like a little coil with three plugs in it that goes inside the Box but you probably want to replace that anyways $120 or best offer.
