The other day I bought a '67 dual resevoir master cylinder for my '66. I heard that it's a bolt on swap that makes the car safer. I see that is has holes for 2 break lines as opposed to the original which only had one. My question is what are the parts I need to do the conversion? I know I need the 2 break lines but also I need a distribution block? Not sure if that's what it's called. My current setup has just one hole for the break line. All help is appreciated. Thanks for the help.
