Hey Jerry - did you look at just an alternator and water pump option more geared to racing?
Another piggy back application I could see is 'correcting' the car setup that puts the alt into the a arms on the old cars. Relo the alt somewhere with some brackets and a new belt.

I'd be in the market for both of those callme
