I'm assuming it's a standard stock style alternator in your car. Back in the 60's and 70's cars didn't have a ton of electronics so they didn't need very powerful charging systems. If all your cables are good and you have a decent battery almost every older car made you can buy a high amp alternator that should fit in the factory brackets. A lot depends on how much stero system your running. If you have amps and subwofers you should run a good battery like a optima gel cell and a high amp alt. If it's just a aftermarket stereo with 4-8 speakers and no amps usually u can just use a good battery as long as your alternator is actually charging like it should be. 1 last thing you can do is buy an aftermarket pulley or pulley set. That basically works by making your alt spin faster and making it charge more.
