It's sort of amusing, in a potentially tragic sort of way, to listen to people who think the folks who designed hydrovac-assisted brakes could have made these big trucks stop just as well without spending all that money. I guess those guys were just determined to waste thousands of dollars of GM's money for no reason- - - - -right?

Not sure I understand the question ? My 1969 Loadstar fire truck has hydro vac and it works just fine was more looking into a dual master option if someone has found or used a compatible unit with minimal modifications I probably was not articulating my intention correctly.
