Although the voltage regulator is working, it’s an aftermarket with the wrong mount pattern so it’s being held in by only one screw. However, yesterday I came across what appears to be a new or slightly used Delco-Remy 6v positive ground unit, 1118303E, that has the proper mount pattern but it doesn’t match any numbers for voltage regulators in the parts book. Is this a replacement part number or would it cause any issues if installed?
