My brother has located a 1972 250C automatic
Oh, and the four-speed automatic does not have a torque converter, only a fluid coupling. (Not sure that means anything, other than it has a low first gear to make up for it.) The dual Zenith carbs, when they're working right, work very well. They also are fairly trouble-free if they're not broken. It can be hard to find somebody who knows how to put them right, however. But once right they ought to stay that way for quite awhile. (And yours may be just fine.) -- Jim
