I used a Wilwood drag race kit but I swapped my other car with junkyard stuff....might be tough to do with the 65..not sure what fits. You will have to change the master cylinder and make sure you have no residual pressure valves in the system between the master cylinder and the calipers...I think some had them in the master and some in the distribution block/proportioning valve whatever ya call it...They keep the fluid from being forced back to the MC by the springs on drum brake set ups...If you have them the calipers will not release correctly.
