I would think that just about any show that works on older cars would be able to help you, and I am not familiar with New Jersey, but over the bridge in PA you have the Mustang Barn in Souderton. I've had them do work on both of my Mustangs over the last 30 years and they are very good. I also heard a rumor that in Marmora (on the Jersey shore near Ocean City) there is a garage named Fred's garage and that he is the former owner of the Mustang Barn, hence he would also be a good source. Good luck!!
