Did you do away with the Hydrovac system and did you use a floor frame mounting mastercylinder with booster like you can get off ebay for a 1/2 ton or does it need a bigger booster and cylinder.It sounds like a grest idea
my truck is a 1951 ton and a half with a hydrovac that needs rebuilt anyway so if I can do away with that and go with a power booster and dual master cylinder that would make things clean and simpler
