Sounds like 3.08's to me. If they are the original ones, get the axle code off the door jamb tag and post it, I'll tell you exactly what's in there.

I'd jack the car up, spin the tire and count the rotations of the driveshaft. This takes the speedo gear (possibly being incorrect) outta the picture too.
