I may just try a spacer or a different booster assembly. My friend/ mechanic thinks he may have a source for a new, smaller booster. He even suggested "hydroboost" from a 70's lincoln or something like that. (runs off of power steering pump pressure)- we'll see. Am thinking this will also be too heavy of a car (3900+/-) for what I'd like. Instead of the 77 tbird, I may buy one of his late 60's mustangs or his fairlane to drop this powerplant into. More contemplating......
