The alternator on my '65 K code San Jose Mustang is the original one that came with the car and I want to get it rebuilt. What I'm not sure of is the finish I should be shooting for. I recently had a carb rebuilt and they put it through a tumbler that did a terrific job of returning the finish to what I believe is very close to original, and I think I would like to do the same with my alternator's body. Does anyone know if this is a good idea for an alternator's finish? And if so, I could use some suggestions where to take it or send it for the rebuild. I'm in southern California but have no problem boxing it up for shipment if there's a shop that has a good track record. Thank You!
