update to old technology

[66fastback]

When I purchased my alternator, I just looked through the JC Whitney catalog, and found a generic 80 amp GM single wire alt. I didn't really have to know what it was supposed to go on....

I think their alt.'s are pretty standard from about mid seventies to the late eighties. The pulley worked fine with my stock pulleys, but I did have to play around with the spacer and the adjustment bracket to get it to line up right. Really easy.

Only thing that I suggest is adding a volt meter to the car. When these alt.'s go out, a lot of times it's the regulator, and they start OVER CHARGING. You can spot it in a second with a volt meter. I haven't had any problems with mine....
