I am wanting to install an ESPAR heater in my 2007 Dodge 2500, but am not having any luck in locating the correct kit for my truck and am told that it has been discontinued. I am hoping to find the parts breakdown for kit part number 82210743. I was told by Lubrication Specialist that this kit is a Cummins-Ram OEM part number. The local cummins shop doesn't know how to help. Any ideas.
