Just listed our 10dn/10si/12si replacement unit for your early GM cars. It's available in 150a and 220a as a bolt-in, plug-in solution for your rides. They have excellent cooling by using one of our hybrid 43g units. The solid copper rectifier, precision balanced rotor, premium NTN bearings and custom wound stator will insure years of durable performance and the 2-year warranty is there to back it up.
Adjustable voltage is available too!
