How many amps for the alternator?

I need to replace my alternator for a 91 none turbo, when I went to a parts store they ask me how many amps does my car needs?

If youre PS equipped you are 100, if youre non ps its 70.

Putting in the 100 amp won't hurt anything

Be sure to order from someone that knows what you are putting it in. I ordered a 100 amp from autozone didn't fit properly then didn't even work properly. When I took it back they tested it and said it worked find. Told them it didn't work in the car and I wanted my money back. After which I took it to a shop that rebuilds alt and starters and had it rebuilt. Actually saved $60 over auto zone.

Put the correct alternator in your car. The brackets are different. Or do a make-shift install, or find the proper bracket if you decide to change.
