need help.. lower balljoint

I am not sure what you have there, but here are more choices for part #'s.

73 - 76 LBJ Moog K781 & K783

72 and older with drum brakes K785 & K787

Maybe since you no longer have the old ones, you could call where you bought the kit and give them the hole dimensions.......?

Also, here is another thread w/ a similar problem. Good luck
