FOX ALTERNATOR UPGRADE. WHICH ONE? HELP PLEASE. NEED ONE ASAP.
 
I have an 89 Mustang Gt Convertible. The alternator is bad. I would like to put in an upgraded larger alternator. I plan to later have a stereo, electric fan, etc.

I know some people are using 94-95 mustang alternators. Can someone please tell me if I purchase one what exactly I will need and instructions on how to do the install?

Are there other alternators from other cars that will also work? I have seen on eBay where there is a seller than sells a direct bolt on no modification and they label it as small housing/casing.

Any recommendations on the best replacement alternator with the smallest amount of modification would be great. Let me know the vehicle make and years. If I have to do modifications please let me know all and any instructions and parts needed. Thanks as always.

I have a 200 amp stinger audio alt in the stock location that was made for the 94-95.All i had to do was splice into the factory alt wire harness and run a 0 ga wire from the +post on the alt to the batt+.and stinger said i had to ground the case of the alt with a 0 ga to.

Thanks guys. I picked up a 3G alternator off a newer Mustang for $50. I have read contradicting information on this next topic. Do I use my stock 2g alternator pulley, or leave the pulley that is on the 3g alternator I just purchased used? I am sure i will have more questions, but that is it for now.

Oh no, not really. I am going to use 4gauge and rewire. Can anyone give me a part number for this fusable link that I need? Like from autozone, advance auto parts, radio shack, lowes? I would like to make sure I get the correct fuse for this. Or just tell me what sytle fuse and holder, and exactly where I want to put the fusable link. If I use 4 gauge power, does the car need new 4 gauge groud? What gauge is the ground on my car now?

just go up to Autozone and tell them what you're doing and
what you're after.
They'll fix you right up.

LMAO!

RBARN, you must have a well staffed Autozone, or you are relying on guys that you shouldnt be. Do you live in a different planet. They guys at my autozone wont have a clue, nor would I trust them.

What about the PULLEY size. I remember reading someone said I could use the 2g stocker with some form of washer. I dont remember? Anyone?

Can I use the 3g stocker?
