I want to convert my manual brakes to power in my 54 Merc. I have an original power brake booster (bendix) with adapter plate to the firewall,which I finally found. Can I bolt this up to my original brake pedal set-up or do I need to get a power brake pedal & linkage?     They also had a tank with the originals. Do I need to use one?   Any help would be appreciated.  Thanks, Mike.
