Coils are the same, unless they're from a SC engine. Those are a different model number, but not sure what the functional difference is. The bracket is indeed different on the series II engines, when it became a combination of the coil bracket and alternator bracket, if memory serves me. Simpler and better for the vibration factor, I suppose, but not at all interchangeable with the older brackets.
