Hotrodroy ---All of the cars that I have built over the years have used a Vega box and cross steering. I have always incorporated a Panhard rod, because I put one on the very first car I built 20 years ago, and it worked so darn good that I have never felt the need to build a car any other way. I have driven some of my friends cars with a conventional "side steer" system where the drag link ran directly from the pitman arm up to the drivers side front wheel. and I found that they tend to 'jerk" the steering wheel whenever you run over a railroad track, etcetera. I don't have that type of problem with the cross steer set-up. As far as a vega cross steer on a suicide front end, I haven't seen one myself, but then, I haven't been looking for one either. I know that others have the theory that a Panhard is a necessity on a cross steer front end, and maybe they are correct. I've never ran a cross steer without a Panhard, to know.
