I do not know of a Drum Brake equipped 1970 G.T.O. I do not see how they could justify creating such a car! Not to mention a 455 H.O. G.T.O. with Drum Brakes! Now, do not get me wrong, Drum Brakes are the least Drag Brakes, or so they say! Of course, they are also the most challenged at stopping a fat G.T.O. at speed!
