early abody ball joint differences?

Call pst or just suspension They can give you the details on which combos work. I had a drum 9" on a early A body and they are all the same for what you are asknig from 63-72. In 73 even B,E bodies share many parts withthe A body. But the A body pre 72 parts will all pretty much go toghter depanding on the spindles disc drum etc. There are some differances. The the pitman arms and idler arms are year specific too and some mount inside or outside the K frame.

You just need to make sure you have the correct ball joint for the controll arm and spindle comdo you are using. There are some that are listed as HD too but they are basicall the same when used in the corect mentioned parts above.

hope this clears it up some?

PS on BigBlock Dart there is more details too.
