I have a 79 trailering special. They are kind of a rare bird. Mine is a GMC, came with a 350/350, oil/trans cooler, 2wd, 12 bolt with ls, hitch/wiring, big towing mirrors and fancy badge by the door(talk about hard to find. I am missing one). I've been told it has a 3/4 ton rear springs. I also have a in bed spare tire hold down. Nice rig!
