I bought from ram man and he's good at listening to what you are using and recommending what you will need to get it to work... I got my master cylinder and prop valves from him and then went to the spot next to him and bought the steel lines from Fine Lines at the Indy meet many years back...
I am converting my 66 Valiant wagon to disc brakes and using a manual master cylinder... That way I can use any size cam that I like and don't have to worry about vacuum for the power brakes...
