If the PS fluid is ruining your alternators, you are getting some really cheap alternators. The wingdings are sealed from contaminants and should be fine. All of our cars have spent years bathing their alternators in P/S fluid drips and road grime. This isn't a new thing.
Did you ever swap the P/S pump and keep the tank? There is a special O-ring to seal the tank to the pump, which you can't get from your local parts or hardware store. Attempting to do this without the proper size O-ring will lead to a certain leak.
What kind of alternators are you putting in? Are they all coming from the same source?
something out of line with the pulleys maybe?
how did you determine your ALT was bad in the first place
When you tuned the car what did you set your idle rpm for your cam?
Are you having the alt tested because you are having a dead battery or basing this on the output voltage on the dash?
Reason I ask is if you are going to advance or autozone to test the alt, if you don't tell them you are running a 25% under drive pulley the alt will not show in spec because it actually will be spinning at a different speed even if you hit the target rpm like 2000rpm. You need to add the 25% to that rpm and than have the alt tested and it will probably output within spec at the right rpm.
Need to know more about why you think the alt is the issue. The PS and alt maybe unrelated but the alt maybe a combination of low idle speed and your UD pulley

whats the time gap between low batteries and is it possibly a coincidence could something in the system be draining it between drive periods?
hopefully this all doesnt come across as insinuating anything i'm genuinely trying to help just thinking outside the box a bit
the four pin connector is responsible for telling the alternator when to charge (Im just a little fuzzy on the how and why) so it could be related to that as well.
If the parts store isn't honoring the warranty, that's another problem. The P/X fluid thing is BS. I doubt there is a "fluid contamination" rider on their warranty and even if there is - just unload a can of brake cleaner on the thing before you take it back and they will never know the difference.

I agree on both counts.
I would suggest going with either a GM reman (these are better quality than the chain parts store re-builds in my experience) or a good name brand new unit, such as Powermaster.
As for the constant PS leaks, if you have replaced the entire pump and reservoir with a new assembly and it's still leaking, then this is a low quality replacement. They didn't leak like this when new off the assembly line, so replacement parts shouldn't be leaking out of the box either. Again, I would go with a higher quality brand, assuming you're sure the leak isn't due to a damaged/deteriorated line or fitting and is definitely coming from the pump itself.
