Not sure i want to go that route yet, got to visit a guy just down the road from me parting out a bunch of 73 up Darts and Dusters just to see if one of them might be an AC car.
In the mean time I have to finish up working on a friends original 20K mile 72 Duster /6. Man this thing is a time capsule. Original plugs, cup seal orings, wires, cap, rotor, points, hoses, belt everything. Pentastar and part numbers still visible on most of the components that had them. Original interior beautiful and not all cracked, superb inside trunk and a tire jack that looks like it was never used. Western Auto Polyester tires D78-14s still holding air. Unfortunately it sat too long, changed the shocks, fuel tank and sending unit fuel hoses, the master cylinder and all the wheel cylinders. The /6 after carb rebuild and tune up and water pump runs like an old singer sewing machine. You just gotta smile every time you look at it and its simplicity.
