Default LS1 vs LS2 Alternators? Differences.

Well, I'm in need of an alternator for my 2005 Corvette (fire damage, no need to diagnose if it's okay - I may get a reman, but still need the part number which is melted on mine). The problem is that I see quite a few part numbers for C5/C6 alternators.

What is the correct PN for a MN6 2005 alternator?

What are the differences between the various alternators? I hear about variances in the connector pins and 145 vs 150 amp, but I can't get any specific info.

I've seen these part numbers for C6.
- 25888970
- 11591159
- 11591160
- 15841234

Plus these C5 numbers:
- 12533437
- 10316182
- 10353400
