We`ve done a few over the years in our show both for ourselves and customers. IMO the first thing to do is unbolt the the whole front subframe at the fire wall,remove it from the car and make it go away. We`ve had godo luck with Heidts front end for the box Novas. It`s not the pinnacle of suspension design but it`s competent and really transforms the car. With a few geometry tweaks and upgraded brakes they actually handle and work very well. Mark SC&C
