Any GM 10SI one wire will swap in. I use a PowerMaster one wire in mine. They are made in USA. Any one wire\self exciting alternator will work. You do not need a high amp output. A 35 amp will do but, it might be hard to find anything under 60 amps. Keep in mind One Wire alternators need to reach a certain RPM before they will start to charge. You want to pick one that starts charging at a low RPM.
Powermaster also offers a "Generator Look Alike" which is a one wire alternator inside the original generator case. Page 54 is the start of the generator look a likes. For a CJ generator look a like you would use a Powermaster 82051 for 12 volts or a 82057 for 6 volts.
