1978 Brougham ac unit

[PaPa Camper]

Bought an 1979 Dodge Brougham camper late last year. As I was going through it I found out the ac unit doesn't work. My question is what do I need to look for when buying a new one? It is a flush mount or low profile inside the camper. Not for sure the exact words. Also have clearance light issues, but I'll put that in another post.
