Need Help with Front End kit

The key to all that is the upper and lower balls. You should be able to compare them to the 68, and the 73 up stuff should be different. "I'd bet" as said above, you have 73 / later stuff, there. Maybe you got "the one" late late late production 72............LOL

Or maybe someone converted that car before you ever got it. Hell, "back in the day" "we" would have thought nothing of doing this.
