Those guys are builders, they are not professional builders. You are seeing a problem for sure. I think the radius rods was a good suggestion if they are put together properly. Those 2x4 radius rods are scary looking. The bottom one has a bend in it, take a look at whether it's been welded and ground down there (without fish plates) or whether they've just been bent. You need a good local race car or fab shop to look at it. See if those arms are Mustang or something you can replace with good aftermarket ones. If I can help let me know.
