If you like traditional looks and reliable, modern performance, you’ll love this cool Flathead 1-wire alternator. It has the look of an original generator, but is really a 12-volt, negative-ground alternator that produces 60 amps at idle and 75 amps going down the road. This model is designed to fit 1949-1953 Ford & Mercury Cars and 1948-1953 Ford Trucks with Flathead V8s and features a simple one-wire hookup.
We offer this one wire alternator in black painted or polished aluminum, and both include stock-appearing mounting brackets (the stock fan carrier bolts to that bracket) and pulleys that accept wide 5/8” belts.
- Easy one-wire hookup
- 5/8" wide belt pulley included
- If using 3/8" wide belt, order pulley # 91067178
- Uses stock-appearing bracket and fan carrier bolts
