Starkweatherr,
If you look through the building of my 56 5100 you will find that I used a hydro-boost with a bracket that uses the stock through the floor peddles. I got it from ABS Power Brake INC. It came complete with the bracket, power booster, master cylinder and remote reservoir. The bracket mounts to the stock master cylinder mount and the guys at ABS sized the master cylinder to the 2 ton's brakes. ABS is located in Orange, CA. and can be reached at
(714)771-6549 they have a very nice web site however my computer crashed so I don't have the link you may want to try a few variations of their name and see if it works.
