ALternator question 1970 Swinger 340

Gang, I'm a new member in CT and recently bought a 1970 Swinger 340. The car is great however the Alternator does not appear to be charging. The engine compartment is close to 100% and now I appear to need to have the alternator rebuilt. Any recomendations where to turn? I need to get it serviced by someone who will be careful with it. I'd love any ideas

Thanks Terry 203.644.8403
