Struts rods always produce a conflicting arc with the lower control the further the control arm moves. No mounting method eliminates that. The best part of an adjustable rod is to put the lower arm into its best arc position while minimizing the conflicting arc. If you onl;y use it to dial in additional caster, you will increase the conflict of that arc.

I've thought about a tubular strut that screws into a Camaro ball joint on one end, which bolts into the K frame. Ball joint arrangement allows use of a dust cover, ability to grease the joint, and more articulation than a double sheer heim. Also is easily replaced without dis-assembling the lower arm while still providing the semi-solid mounting method that reduces toe changes under braking/acceleration.
