    we purchsed a front power disc brake upgrade kit for mpb and have painfully:bang: gotten all the lines in place mounted the booster, proportioning vlave and bolted up the calipers and discs. now we are stuck on where to tap in for the vacum line. we have a 302 and theres 2 choices, 1 off of the carb or the back of the intake manifold which also is used by the auto tranny. weve been told to use the tranny tap and use the carb and also been told to use the carb and not the tranny tap.
    thanks for all suggestions

    Guess you should use the carb and not the tranny tap then. Since you have been told that twice. :rlaugh: j/k couldn't resist.
