Help-K member swap 1975 Dart Sport
Just to clarify a bit....the lower control arms from '62-76 can be swapped around if there is no sway bar, or if you're going to add an aftermarket setup. Lower arms with a sway bar tab come in 3 different versions. A is the '65-6 version, B is the '67-72 version, and C is the '73-6 version. A and B will interchange with just a slight difference in the eye opening. A has a built in washer where B does not. C is all by itself and uses a different sway bar tab location. The upper control arms need to match the spindle year. '60-72 use a small ball joint stud, the '73-6 uses the big ball joint stud. Both setups will fit the car, just include all the parts from a particular year. Now, if you plan to use your '75 power steering gear on the '68-72 suspension assy, the pitman is going to be a problem since you can't mix and match the steering components. '75 had a big P/S pitman shaft, and '72 and older uses the small pitman, like the manual box. IIRC someone makes and conversion pitman, but, check on that to verify should you decide to go with power steering.
