Tail pipe will not be long enough for a chrome tip. I also believe he has a body plug missing to allow the exhaust into the car. A station wagon with an open back window is known for this. The reason some have a top deflector.
Wagon tail pipes normally go out the side for that reason.
Deflector was to blow clean air over the back window to keep dust off. You have to remember there was a lot more dirt or gravel roads back then. The dust would swirl behind the flat wagon back and settle on the glass and sheet metal. The deflector aided that. My 82 Blazer had one also for that reason.
