These are a must for running the quartz sealed beam headlights or if you just simply want a more reliable charging system.
These alternators are new and include a five year warranty. Includes an adjustable bracket that allows the alternator to move 1/4" front to back. Sold outright, so there is no need to send in a core. Comes with tension brace.
Now they have the new Max-R pulley that drives at three times the engine speed. Fits 1928-31. 12 volt units are negative ground only, and 6 volt units are positive ground only. Mounting bracket is adjustable so the alternator can be shifted for proper belt alignment! If you are running the quartz 6 volt bulbs, it is best to go to the 60 amp unit. "Genuine Nu-Rex," U.S.A.
