Tony, I recommend Precision Automotive on Old Dixie Highway in Delray Beach. Rob has had the business there for 27 years. In the year since I bought the car he's worked on my front end (kingpins/bushing/swaybar) replaced my radiator and fuel pump, rebuilt my differential even replaces all the bushings in my shifter. He's even GIVEN me parts that were on a new/old stock transmission that he had on hand. He allows me to supply my own parts if I find them cheaper ($250 for the rebuilt fuel pump instead of $485 for new). The car is quite mechanically sound now.
