Generator or alternator ?

[Bob NH]

Just finally got the "powergen" alternator checked out and as suspected, no good and can not be repaired ! This came on the vehicle and why anyone would spend that much is beyond me. My question is, Joe's antique has a nice kit for not huge dollars, would it make sense to go with it or should I be looking for an original generator someplace ? Not a show vehicle , just want to have fun driving it without troubles!
