Was flipping around on rock auto,and seen they have Master cyl.and booster pkgs.available for the Monte SS.Noticed though they list and single and dual booster.Photo also shows there is a significant size difference between the 2.Would be safe to assume that the choice would be the thinner one,or would the larger goofy one fit the same.Or is there another vehicle that can be crossed referenced.Could use some input here.....
