ball joint issues

Chuck if I remember correcly the bolts just braek as they get old. In the mag article they narrowed it down to 9" front drum brake cars. My 65 Cuda had these and I can't remember if the bolts are the same on the later or Disc brake cars or not. I just put the best grade bolts in I could get when I put my 10 " drum spindles on for my new disc brakes. I tried going through some old Mopar mags that I have and just gave up as I have saved so many.
