Q&A for a`65GT
I think scarebirdbrakes.com is about the only brake swap to keep the sbp.Unless you can find a factory 4 piston setup, There was one forsale here in parts. the 323's will be good for a cruiser, if your gonna race it any i'd go with the ss springs when you swap the rear, i've runed the 6 torsion before with no problems long as there not woreout and your frontends in goodshape
