Just purchased an '96 2500 Ram with a cummins in it. SLT Laramie. The difference between that & my '95 gasser with the same option SLT Laramie is that the diesel doesn't have the outside air temperature & fuel calculator on the headliner, it is just a pocket for storage. Was it not available for the '96 diesel? Or is it not just not there as an option? If that is the case can it be relocated from the gasser to the diesel & if so what do I change or need to have it work in the diesel? Thanks
