So no little tag under a cover bolt. No spid. Time to jack up a wheel and put her in neutral and count how many times the driveline turns to one wheel turn. Now if it has a powerlock it may not turn easily. It will be half of your actual ratio. 4.10 would give 2 turns on the driveline, one turn of the wheel. Now if your handy with your wrenching skills I can walk you through a RP swap that you can do for less than 300.00 bucks if it's a 4.10 a hundred more if it's a 4.56. Barry
