I talked to a guy at the Stainless Steel Brake Corporation that had great knowledge of Mustang brakes and he said that I can use my factory drum spindles for disc brakes on my '66 V-8. He said the bracket that holds the calipers bolt right to the spindle when the backing plate for the drums bolt. Anybody know if this is true? He said I can get these brackets from NPD. Any help here guys? Also, what booster do I need on my '66 so I can put the duel reservoir master cylinder on it from a '67 up? Thanks for all your help!
