Re: WK2 Overland with Off Road Package
If you have a V8 and are expecting to get rear ELSD (in a 2012), it is only available as part of the ORA or as part of the summit.
The other pieces, skid plates/ wheels/tires/tow hooks, trail-ready badge can be purchased and retrofitted, although the tow hooks are a PITA. You may want to consider getting an install price from the dealer as part of the sales deal. Fuel tank skids require a bit of effort, everything else can be done in about 30-45 minutes.
