So I'm finally getting around to making some improvements to my wagon. We've been too busy driving it since we bought it. We've taken it on a few family trips, and while the car rides great when empty, load a family of five and a week's worth of luggage into it, and it is scary at freeway speeds. So, the first round of improvements are in the brakes and suspension. This car doesn't need to out-stop or out-corner a Porsche, I just want it to be a nice driver. I have a '73 Scamp in the garage that is getting upgraded suspension and brakes, so I've got a lot of factory parts to use, if possible. My plan for the wagon is to use the V8 torsion bars from the Scamp, and the anti-sway bar if possible. I know the later cars are wider, but will the sway bar work on the early body? If not what are my options? Was there a factory bar on the early cars? I've done a bit of research, but I haven't found anything other than massive aftermarket bars, which I don't want for this car.
