He does nice work! What was replaced alternator wise?
- Diode Trio, Brushes, Springs, Regulator, Bridge, Bearings &?
I'd suggest that you bag & tag all of the takeoff parts for future used due to the originals superior quality to anything new

No rain or

intended, just keep all you have for future use as needed IMO.
I can tell you that the current parts available are no match (is anything really?) for what I used to sell back in '80s..
It looks nice! Hope he "clocked it" right
