I bought a Sport in Massachusetts, February 1978 from a dealer as a left over. I was 18 and it was my first new vehicle. I sold it to the guy across the street in 1979 because gas was coming up on $.80 a gallon, too expensive at the time. The first thing my neighbor did was pull the stripes off and add an aluminum camper shell. I don't know what he did with the light bar.
I bought a 77 short bed fleetside last year as a utility truck and eventual project truck. It's a California truck so the body isn't in too bad a shape. I plan to do a frame of restoration someday but it's not a priority at the moment. For now I'm collecting information and parts.
Here are some pictures from 1979. I don't have any paper work from my first truck but I'm pretty sure that there wasn't much to the Sport package--some decals, white rims, locking chrome gas caps, and chrome parts. Note the chrome bead on the dash bezel. I added those big truck mirrors. They killed my gas mileage but I could go backwards like Mater
