I have a 76 GMC long bed DD. Got it for free w/o motor and threw in a 350 I had laying around. Been beating the hell out of it for 7 years. Got it smog ready, but it's still a pita. If I were you, I would keep my powder dry and wait for a Ramcharger. You can find them for a better price than that and if you find a 74 or 75, you don't have to smog it. Remember, Plymouth made Traildusters also.
