Marc - the Delco alternator I noted fits a '73-'74 Pontiac Grand Am, LeMans, some Firebirds, and Cad Fleetwood around 1980. It is rated around 104 amps, but that seems to vary somewhat depending on who you get it from. I picked it out of a NAPA catalog that showed its physical dimensions as well as rating. That's why I noted the Beck-Arnley number, as it should be available most anywhere.
