1974 Dodge Dart lower balljoint rubbing???

Assuming the taper is correct.:D

Well yeah. But the bolt holes line up, and Ma Mopar changed the bolt size and spacing more than the taper size on the lower ball joints. So unless something was made incorrectly they should work.

Now, that said Moog once sent me a castle nut with no threads inside, so, anything is possible. That was the last time I bought moog stuff. Their quality is pretty terrible now.
