1965 coupe, I6, auto trans, manual brakes Has anyone done a drum to disc brake conversion using Scarebird brackets lately? I am thinking about do it on a 65 Coupe with an I6 and auto transmission. I want to stick with the 4 lugs so I do not have to change the rear end. A couple of other questions; Should I install a power booster on the brakes? Do I need a proportioning valve? When would one need a proportioning valve? Can I use the Scarebird bracket to change the back drums to disc brakes? What else should I be considering? Thank you all for your help.
