Charlie, I've run the Motorola on my Javelin for several years with no problem. It's a quality rebuild that I bought at AutoZone. Many people switch because they need more amps. The biggest Motorola is 55 amps. And some people want to get rid of the external regulator. The Motorola is definitely an older design. AMC also used some Motorcraft alternators. My son's 78 Matador has a Motorcraft. I found a chart in my Chilton's manual. According to this they switched at different times depending on the engine. For the I-6 they started using Delco in 1975. For the V8 they used Motorola in 1975, Motorcraft 1976-1977, and Delco starting in 1978. If this is correct then you probably do have a Motorola.
