Default 1970 Grand Prix Alternator Number

I recently purchased a 1970 Grand Prix SJ. The original alternator has been replaced with an AutoZone replacement. What would the original alternator number be? It is equipped with A/C, power windows, power seat and heated rear window. I am assuming it would have had a higher amperage alternator because of these options. Thanks for your help.

The one on your SJ should work!Lol. Does your car have the original alternator? It is equipped with the same high amp options.

That's what a couple of people said. Thanks for your help. Now, I have to find one for my 09C production car.
