Ok, there is an 08 Commander at the upullandpay and the diff is the right gear ratio but not sure if it has the electric locker. I do have the part number tag but can't find jack online!!
Any service tech or dealers here that can get a possible read? There are two part numbers. One is: TPLSF123810293
The other is: P52111369AF
There is a 3.73 before the P in the second part number which I know is the gear ratio. Not sure if that's needed to put before it or not when searching?
