I doubt the Dakota heat/AC will fit in a 1934, those vehicles are very small. There wasn't enough room to install a Dakota box in my 39 Dodge pickup, it wasn't even close. Just mounting a heater core with a fan attached and a small box around the outside was a major project. If you want heat and AC in a 34, your probably going to be stuck with one of the major after market compact heat/AC vendors out there like Vintage Air (their name is just an example, I have no experience with them or their products).
