Sometimes nothing seems as simple as it should be or sounds.The people on here are really good and they will point you in the right direction.Taking on a project like this by yourself and at your age is really great.Gl. Sam
Half the "problem" is that Chrysler changed, or improved, their specs for components over the years. You must decide whether to keep your car within original "specs" or change to the "upgraded" specs. Generally speaking, Chrysler made the changes for very good reasons. Bigger is generally better, specifically concerning ball joints and wheel stud dimensions.
For my money, I like to go with the "improvements," such as the bigger ball joints and wheel studs. This seems sensible for cars used as drivers as opposed to car show trailer queens. It is simply the evolution of engineering.
