Help with 68 A body lower ball joint.

There are two different shaped/size lower ball joints out there for this period Mopar. One fits the '68 and the other is for the years after that. Try having the look up ball joints for a '70.

Someone with more exact knowledge of the part numbers will hopefully chime in.

I picked up a set from PST, and they only lasted a few thousand miles. Try using the Moog problem solver ones.
