this would probably be simple for a good fabricator. and I am not sure if its been thought of yet. everyone says that a side-to-side with a 2-link is not possible....but what if someone were to put a joint on the end that could twist as well as up and down. You would definately need a panhard for the setup but it seems to me that it would allow for at least some side action without tearing the perch completely off. It is just an idea so dont throw a 4-link bar at my head
