68 camaro that came with 4 wheel drum non power brake set up, with a three speed on the floor. I am switching to an automatic. so I had to change the pedal set up out of a 1968 firebird. then I figured I might as well put in a power booster and new master cylinder but there are about 1 million choices out there, most of which are for a disc/drum set up I am having trouble locating a set up. any ideas or suggestions. what started as just put in a new brake pedal has turned into a huge pain in the ***. I tried just putting in a automatic brake pedal but it sat up way too high

 

I had enhanced power brakes to my car and planning to attach drum set too.
