I am almost finished with a total rebuild of my suspension and added front disc brakes as well. The disc brake kit came from classic performance parts, as did the front end rebuild kit. I have a booster from Master power brakes. The rear trailing arms are from early classics. The control arm shaft assemblies are from NAPA. So far, all of the parts are supposed to fit stock applications and everything has fit together well. The suspension is finshed and I still have to plumb the new brake lines before the brakes are ready. The ball joints are a little spendy, but not that significant compared the cost of the whole project. Here are some before and after pics.
