Default rear axle question

Quick question for the collective. I'm looking at a '97 with a performance rear axle.

Is that the 2:87, 3:14, or the 3:42's?

Thanks all.

performance axle means two things:

1. that the C5 has an automatic tranny

2. that it's the 3.15 rear ratio.

to be certain, read here:
