Mopar Action magazine put together an A body for handling and straight line. Called it the green brick. You could probably do a search for info on it on their site. Yes, just looked and the front page of the website has a link for the green brick. From what I remember of it they used moog problem solver upper control arm bushings, urethane strut rod bushings, welded a gusset on the upper control arm mounts and perhaps a few other mount points to keep things in place, used '74 up C body tie rods and sleeves, a front swaybar (could just probably buy one of the aftermarket ones really), put in frame connectors, larger torsion bars, koni shocks, some decambered springs in the back with clamps with a forward angled set of shocks added. Basically you have four shocks in the back. A fast ratio manual steer box. Basically it. Mostly factory swap parts from what I remember. Usual disc brakes up front etc. Might have missed a few bits, but have a look at the link. I've not clicked it, but should give the info. If I remember right they were ripping up mega dollar exotic cars at the track with it and when they ran it at the strip I think it ran in the 12's. I'm sure someone can chime in and correct that time if I remembered wrong.
