You'll need to know the axle ratio (3.08,3.55 or 3.70) to figure out the gear

Generally speaking the L82, auto received the 3.55 rear end.

L48 the 3.08 however in some circumstances a 3.55 was in place for high altitude cars..

This is why you need to check for yourself what rear is in the car now.
