What were some of the smaller (single pulley) pulley sizes that were used on the old round back/ square back alternators ? Who sells them ?
Not sure, I'll check thatLook for one that is 2.5 OD.
but the real thing is what is the od of your crank pulley.
The alt pulley should turn about 2.5 x faster than the crank pulley
