ok thanks for the info I thought it might bolt up ok I may purchase another remote hydravac or just not run the power brakes never had power on any of my other 56 ford thunderbirds seemed to stop fine just I like the security of dual master cylinder thanks
I am thinking about installing 69 mustang dual master cylinder on 56 bird was wondering what I would get into with mounting two bolt master cylinder where four bolt was before also if I could get away with runing hydravac on one side of system and if so which front or back
