I'll bet that means 4.56 or 4.88 gears, probably 4.56.
Assuming you don't have a locker or a limited slip rear end, you can find out. Put blocks under both front tires, in front of and behind the tires, put the trans in neutral, Parking brake off, jack up one rear wheel, mark the bottom of the raised tire,
crawl under and mark the driveshaft. Rotate the driveshaft and count the number of rotations of the driveshaft that are needed to rotate the tire 2 revolutions. That number is your gear ratio.
If you have locker or limited slip, you have to jack up both rear wheels and count for one turn of the rear tires.
