I would like to put power brakes on my '51 Chevy Styleline. I don't like available conversions which push access to the master cylinder under the front seat, and would like to go through the firewall. Can anyone give me information regarding which model master cylinder I can use, (convert from something commonly available in a junk yard etc.). Also suggestions on hanging a pedal. I am thinking to find a readily available low cost set up and make things work through the firewall. Thanks for your input.
