Aha of course! The shock bolt eye is much closer to the old endlink's mount axis than the E-body tab location on these arms (heck, OEM arms have the shock bracket almost longitudinally parallel with the swaybar mount hole)

I could use a longer + stronger shock mount bolt and use an endlink with an eye bushing/threaded rod construction to attach. There would be a mild amount of deflection on the rod end, but that gets me in a much better place than anything else I've come up with.
