Ok I should have been more specific. I do know what years the came on, disc and drum car differences, and styles.
But the socket diameter is what I am in need of.
The small Ball joint is 1 3/4" nut size and the large is 1 7/8", not sure about the threaded portion of the ball joints.
The 72 and older has the same ball joint on disc. and drum cars. I assume most of the 73 up cars are the same as well but as I said above, I have found some 73's with the small ball joint.
