I am well aware of the KDP, and the need to have it replaced. My problem is I just bought this truck, and the guy seemed to take good care of it, and made some decent upgrades to it. I don't know if the KDP was fixed or not, and was wondering if there was a way to tell with out tearing into it. I can't ask the previous owner since he passed away and I bought the truck from his mother who knows nothing about the truck at all. Any ideas??
