I see posts here from guys who rebuild transmissions and engines who are scared to death of rebuilding an alternator. Rebuilding your own core assures that the cases match, the date codes are correct, the pulley is correct and the workmanship is good.
For round back get a set of bearings and this electrical kit:

On the round backs, the only tricky part is soldering the diodes in. Make sure the connections are clean and mechanically tight. If you can find some, use rosin core silver bearing solder. Regular rosin core will work but silver is better for heat tolerance.
This was the first rebuild project on my first Mopar. My 62 Valiant stumped the local mechanics in the small town I where I was going to college. When they could not fix it they recommended I convert it to a generator. I thought that was stupid and found two open diodes on the back of the alternator. I replaced them all and the brushes as well and reassembled. That was in 1966. The rebuild lasted the life of the car.
