Gets more confusing. Napaonline crosses the O'Reilly R118 to a VR25 which only lists as being used thru 49 models. The one Napa lists for the 51 200 is a VR22. The number O-D mentions from the old catalog appears to have been replaced and is NLA. On the 1071 DrewLA found, Napa buyers guide lists it as used on 54 models.

Whichever you wind up using, Packard specs say the 54 cars have a 45 amp generator whereas the 51 specs lists it as 40 max and the earlier ones 35 amps max. If you use the Oreilly regulator you might want to take the car to a shop with the proper equipment and verify it is set and regulating properly. Worst case if set too low is the battery doesn't charge but if set too high you don't want another generator with thrown solder. At least make sure the regulator can't call for the generator to exceed its capabilities.
