I need to find an automotive alternator that fits my O-320 Narrow Deck engine. I prefer a Nippon Denso unit. All of the suggested part numbers found with the search function appear to be for the newer wide deck engine case which has a different alternator mounting boss system. My engine has the bracket that bolts onto three of the case half bolts. The alternator mounting ears on the bracket force the alternator I bought to be too far forward or rearward for the pulley to line up. Anybody have a solution to this problem, other than going to B&C or PP?
