Did GMC ever make a similiar version to the Sport? Back in 1987, I was looking for a short-bed fleetside and test drove a 1979 GMC Sierra Classic short-bed stepside with a 454 and nearly identical options as the one posted in this thread. I didn't buy it because it was a stepper. What an idiot...........Back then I would have hot-rodded it anyway and ruined whatever collector value it had, so maybe it was a good thing I didn't get it.
