You can have the vin checked, or jack up the rear end, put the tranny in nuetral, and count how many times thedriveshaft turns to 1 turn of the tire. This will give you an approximate idea.

I would guess the guy at the dealer madea mistake. It is probably 3.73. I don't think GM even offered a 2.73 in 2wd then. That would be rediculously high and undriveable.
