It will mount just like a frame mount master and vacuum booster same parts as the firewall mount just longer lines and of course the frame mount and pedal. You would need to make a bracket/plate for the booster unit to attach to the frame mount but that’s the easy part.

Cal 58 GMC has that mount setup with a vacuum booster below, just put the hydroboost unit there and make a plate to mount the unit to the bracket
