I have a 2014 silverado Z71 crew cab with black leather seats. I thought i would like the bench/jump seat. I don't like it, i found this thread. I see where two different people posted part numbers and pictures. Part numbers are different, but look the same? What is the difference? I just need to know exactly what i can do to do this full swap with the right part numbers. Local dealership is no help! Any help?
