South Florida FABO Brake mechanic needed!

I have a 1970 Duster I am having problems with the power brakes. Is there any FABO guys out there in South Broward County that can help. I am stumped and I am only willing to take this car to someone that knows these cars and cares about them. I suspect Booster or vacumn issue, but just want this issue resolved so I can start driving this car. Thanks any feedback or PM would be great.
