On a '57 Ford with a 272 V8 I installed a single wire GM 65 amp. alternator in the original Ford generator location. It required a small spacer to line up the belts on the main hanger and I used an oversized nut (about 1/2" I think). For the adjustment I used a turn buckle. The turn buckle worked great for adjusting and the car was my daily driver for years.
I know I had a 12v system to start with but the mounting will be the same. Don't go back to the generator setup. I remember I started out that way. I had installed an ammeter and you could see that old regulator pulsing and the generator just couldn't put out the poop. ...and besides, think about the weight loss without that regulator? Good luck, r
Looking for the right '57 Ranchero for a "keeper" this time.
