I know at one time someone had a part number listed for a CS style alternator to fit the stock brackets for a 69 big block car. My 69 Caprice is undergoing some resto things at the moment, and it would be the perfect opportunity to upgrade to a more modern charging system. I've had my spats with the original setup and am done with it! I plan on purchasing a complete wiring harness from M&H, but am unsure the better alternator to get, and the one that will fit. The alternator mounting points are 180 degrees apart and the measurment is just shy of 7" across. Any thoughts out there?
