Either bracket you use should be fine for the vacuum line from the back of the carb to the booster. You might need a new vacuum hose to get around the bracket if it currently runs through the space the bracket would occupy, but otherwise it shouldn't be a problem. It's up to you which one you want to use. It looks like mine is like the Mr. Gasket part found at Oreilly's, so there isn't a return spring mounting location on it. you could bend a piece of metal to accept the spring and bolt your fabbed spring bracket in one of the threaded holes in the back drivers side of the intake manifold. You'll just need to figure out how to connect the spring to the carb (eyelet we talked about earlier).
