Would need the shop manual to look that up. You can jack up the rear of the car and put a chalk/paint mark on the driveshaft. Place car in neutral with parking brake off and assuming you have a positraction rear turn a rear tire one complete revoltuion while watching the mark on the driveshaft. If it turns 3 1/2 times you have about a 3:55, 3 1/4 times about a 3:23, etc.
