Lower moog ball jt 64 cuda 4 drum left side

hey Arco440 , I am running into frustration. Advance Auto (Ohio) is saying Moog K785 for the right and K784 for the left, with no luck on the left. On the one link Oklacarcollecto has (above) their compatability checker says K787 will not fit the 64 barracuda base. remember I have 4 drum. I will try to find out if they are the same. mancini racing (mopar supply says TRW / Moog K787 fits 64 cuda drum...go figure!
