BTW if you need a new regulator for your “mando” korean alternator, the local starter shop told me they were about $50, the same price as a fully rebuilt 60 amp delco 1 wire alternator that will bolt right in its place.
Mine was overcharging at 15.3 volts (no bics trouble, But cooked 2 year old battery) Since the bearing were rough to I retired it for a “cheap to fix common as nails“ delco
My 853 had a 5/8 wide v belt, so I had to die grind 2 little flat spots out of the bore of the mando pulley so I could use it on the delco. I also had to put a extra washer behind the pulley to keep from crushing the fan.
Other then that it was easy.
