The running boards are numbers 6MP94KXJAA and 6MP95KXJAA (left and right, not sure which is which). The mounting hardware is 68193128AB. I went back to the dealership I purchased the truck from, which is not my home dealership. My home dealership told me they weren't in the Mopar accessories catalog and would not help me further. They are very pricey, so you've got to REALLY want them. I really like that they tread matches the tread on the back bumper and the all weather floor mats. It's the extra sort of detail I appreciate. The "list" cost is $944 each, and the dealership charged me $750 each. I think if you added them when you built the truck it was an $800 option. I don't have much of a relationship with the dealership where I bought the truck, and subsequently the running boards, as they are about 100 miles away, so I have no idea if they were giving me a good deal or marking it up because they don't expect future business from me.
