What did a C20 have for a orginal bumper?

[truck69]

I am fixing up my Custom Camper C 20 which includes a crate 350 motor..New mirrors..Grill..all chrome trim taken off and will paint it one color. Will have new wheels. When I bought the truck it didnt have any bumper in the rear. What kind of bumper did these have? I am not sure if I am going to get a smooth bumper with the cut out in the middle which I see on most 67-72 trucks that stays right against the body of the truck or the big chrome bumper that sticks out about 6 inches. The truck is mostly to take to shows and around town. Any info would be great.

Thanks. Truck69
