tubular lower control arms

jos15700,
Those must have been tremendous forces since the strut rod attaches to the LCA very close to the lower ball joint. It doesn't quite make a triangle strut arrangement though, so I can see where the LCA can pivot around the strut attachment point. However, if the LCA didn't distort and relieve some of the force, the strut rod might have pulled thru the K-frame. That probably happened in my 65 Dart, since there is a thick welded plate over the original strut rod attachment. That is much harder to fix than replacing the LCA, and the LCA gets destroyed in either scenario. I wonder if the engineers designed it to fail like that to protect the K-frame.
