Starter

I am pretty sure I need a new starter. I am hoping someone could verify my diagnosis before I spend my funds on parts. I am kind of new to older cars, I am used to the computer telling me what to replace.

My 66 Dart 225 sat for 15 years before I bought it and I've recently started working on it. It's been starting fine, but the starter seemed noisy. Then sudden nothing but a click. The battery is new and just came off the charger. When I arch the terminals on the starter with a screwdriver I get a click but no spin. Should I replace the entire starter, or can I cheap out on a smaller piece of the starter?
You might get by with replacing the solenoid.. the one on top of the starter not on the firewall. But with the age of the car, you can be sure that the grease inside long ago dried up and so the bushings for the shafts can well be all shot, gears a bit chewed, etc. I would disassemble it, and inspect it, and see the interior condition and go from there.

Old Car Parts NW is a good source for NOS stuff. I got my oddball '62 Dart motor mounts there. Sometimes the response is a bit slooow....
