Back in the 1960s and 1970s, it seemed that "lower ball joints" were something that some alignment shops would always sell to a Chrysler vehicle owner, slam dunk deal, back then. They'd jack up the wheel, get a pry bar and move the tire up and down to the owner's shock. ALTHOUGH . . . there was a spec for that movement AND with the car's weight on the joint, no slack. So from our experiences and what other Chrysler owners' cars did as they aged, the big bulk of those "worn" joints were really "in-spec" and no replacement was needed. FWIW
Certainly, wear CAN happen if the joints were not lubed as necessary, over the years. Highly unusual for all 4 joints to need replacing, unless you just wanted to do that.
The lower control arm pivot bushing is a hidden bushing that many don't consider to need replacing every so often. To remove the lower control arm, the torsion bars need to be moved rearward, which is more money.
NOW, as to the allegedly needed alignment . . . IF the car was not wearing tires, but eased into that situation, that means the car was in alignment when the ball joints were newer, so replacing them with quality OEM-spec parts should put things back to where they were, which then means the alignment should go back to where it used to be when it was in alignment. Same with the upper control arm bushings.
In getting rubber items, always tend toward NEW rubber than older NOS rubber. Rubber ages and the NOS items are the same age as your vehicle. Shelf life items exist.
Just some thoughts,
