You could pick up a booster from another vehicle at a junkyard or ebay. I believe even a 70 or so F150 works. Maybe too a mustang, if their booster is smaller. That booster bracket is sure out there a long ways too. If closer it would probably clear the end of the VC. It might of been a junkyard find also or could even be an after market from a local parts store. I know others have had this same issue and can better give you some ideas though. Me I'd say either find a smaller booster or maybe it's possible to find a shallower booster bracket.
