LCA's and ball joints - 73 B body
If your guy "Pressed" out screw in lower ball joints, in your LCA's, then your LCA's are pretty much junk.
Time to go looking for a new pair. Your just going to bite the bullitt on this one.
FYI
You can tell if the ball joint screws in, if there are "flats" on it to accept a ball joint socket.
"Press" in ball joints are round, that cannot accept any kind of socket.
