The Hitachi LR series of internally-regulated Alternator was first fitted to North American B210 for the 1978 Model year. It weighs about 2-1/2 pounds more than a stock Datsun 1200 35A model and about 1 pound more than an externally regulated 50A Hitachi. The LR160 60 amp model is physically identical, and was first used around 1983.
