I have a 73 duster w/a 440 installed. The person who installed it removed the booster and built a bracket to hold the master cyl. so that it would clear the bigger engine. The car has all of the original brake stuff (disc's, ect.) but it won't stop and I want to make it power brakes once again. What do I have to do. The local parts store has the booster/master cyl combo for a great price of $109 and I see that mopar perf. sells a master cyl relocation bracket for big blocks. Is this what I need?
