Through-the-floor access to master reservoir. Access is covered by a hatch cut from s rusted away floorboard. Diamonds match.

Improved system. Sealed with the blue boot, and vented via the black hose. Seems the vacuum booster suck air in, and I though it shouldn't suck in road dirt, mud, crud, slush and sleet.

Modification was necessary to the push rod. Needed more length and a disc to accommodate the cut-down universal shock boot. I cut the eyelet off of the push rod and threaded it, while push rod was in place in the booster.

Bulkhead fitting. Tig welded stainless, it goes in the floor.

Inside the cab, bulkhead fitting, piece of hose, and a generic rocker cover vent cap. Lets in plenty of filtered air, and acts as muffler too.

Finished assembly, from right rear. The black heater hose attaches to a tee in a 2 1/4" tube welded to the mounting bracket rear face. The blue boot clamps to the large tube.

View from driver's side. 1/2" Heim joint, fine threaded rod, 3/4" diameter rod drilled and tapped for the 1/2" fine rod at each end. I feel the weakest point of the system is the clevis pin at the pedal, and they hold up well.
