1973 Dart Sport side glass....

I have juggled parts in these cars for years. While many of the parts look similar, they sometimes have hidden differences that make it hard to swap parts from different year cars. The windows look the same but have their mounting holes in different places. Sometimes you can swap entire assemblies over: Regulators, glass and hardware. I cannot recall the specifics but there were years with traditional scissor style regulators and tracks and others with a curved tube that was mounted vertically inside and toward the rear 1/3 of the door. I have had some real bastardized cars, Frankensteined with parts from many different year cars. If you have a large enough parts stash, you can often make something work and look fine from the outside.
Good luck and be sure to report back with your progress.
