Tim,
Your mention of the Mustang club is excelent. I should have thought of it. The NH club is run by Rick Lacross. He has a Factory 5 that he built. He knows most everyone in the state who works on fords. (He is a mecanic himself, working for a volvo dealer i believe) Another good place to ask would be the Factory five forum. There are several active members on that site from your general area.
