sorry i didnt mention it sooner. thanks.

Unless you're hung up on the 'period correct' look, I'd strongly suggest converting to a Ford 3G alternator. They're capable of much higher output at idle and low RPM than 1G alternators, and they're not only internally regulated but the fans are internal as well.
I probably have less electrical load than you do, but I switched from a large case 1G 100 amp alternator to a 3G 130 amp alternator and haven't looked back. One of the best changes I made. BTW, you may find your system is more prone to belt slippage with a 3G due to the extra load at low engine speeds. Some people have gone to double V-belts or serpentine, but I found that using an aluminum pulley, properly adjusted, gave me enough belt grip to avoid slippage and squeal. Aluminum pulleys aren't as slick as steel pulleys, so they do a better job of grabbing the belt. I also went to a turnbuckle style adjuster that allows for easier and more precise adjustment than the old slotted bracket adjusters. Not period correct, but very functional.
