I had a 1980s waggy with a 360ci, 727, Quadratrac, 1 piece AMC 20 rear, and Dana 44 front. It had over 300,000 miles on it and was a good vehicle, especially in the snow. Some of the older ones have a TH400/Dana 20 combo. Stay away from the funky disconnect Dana 44 front. I would look for a 1978ish or newer.
