I have a '68 Cushman Golfster and it looks nothing like that. That said, I have a feeling that the "deluxe" may be reasoning. The steering wheel, front / rear bumpers, and the motor / drive train look the same as in my cart. Can you post up a few pics of the inside area? It sure would be nice if that has the same set up as normal Golfsters and only the body being different.
Here is manual to the regular Golfster. Here's hoping it applies to your cart:
