Thank you all for your replies. I will follow through with as many checks as I am able to do. I measured the bolt holes in the frame rails where the Kmember bolts in and measured the holes in the Kmember; they line up exactly, so I don't think there is a problem with the K being bent. I think that they will just confirm what I already know...the CA is a POS. I just wish I had noticed that before I put the new bushings in.
I do have a set of LCA's in the attic, but they are pre-72. Is it possible to remove the sway bar clip from the bad '72 CA and weld it onto the pre-72? Are they configured the same way otherwise?
