This is a universal under the floor system with the 7 inch diameter double vacuum system.Usually installed in hot rods, but will fit where the old manual system is on the left side frame rail, I don't know if I can say this but I got it through pirate jacks which I found from someone on this site. It hasn't arrived yet but the price was right. Up here in Canada the parts companies that sell them won't adjust for the Canadian dollar so I'm saving darn near 150 bucks after shipping. Same system up here with the mounting bracket runs about 450 as they sell the items seperately and not assembled. I don't believe it has the built in system as there's nothing extra mounted on it like you see in a stock Chevy power brake system. I am mainly concerned whether I should mount a porportioning valve and do they work with the residual valves installed. Bob T
