Default which is the correct alternator?

Guys - I'm a bit unsure which is the correct alternator. I have a 2001 with almost 300,000 miles. The dash went flickery and the battery flattened so i guess my alternator is out. Can I ask advice on the correct part mumber. I'm looking at Denso re manufactured and the two I see are:

210-0458
210-0597

Anyone know which is the right one or whether they both are?

Thanks:

Congrats on all those miles. The 210-0458 is the '00-03 alternator. The other is the '04 & 05 alternator but will work in the '00-03 models. Either will work for you.

I pulled my alternator when I hit 330,000 miles and found that the brushes were almost totally worn. I replaced the brushes and It's been running fine ever since. If your rectifier is shot you're due for a new alternator anyway.
