I have a AC/heat unit out of the rear of a van I am going to install in my 65 F100
It has 3 speeds, both the heater and AC conections point towards the passenger side of the truck
It has 4 tubes coming out of the front of the unit, 2 will go to the dash for defrost
It is around the same size as an underdash mid 60s Mustang unit
It will either be hidden under the dash or installed like a 60s Mustang unit with a 66 full size Mercury underdash AC faceplate
I bought one of the AC brackets that is in another thread, it mounts on passenger side with Alt. on top
