Does anyone know why these do not fit 2020 models? Seems strange to me. I have found them on a few GM parts sites, but these sites list them as incompatible with a 2020 2500 AT4. When I tried to source them from the dealer they could not find them as an option. But i swear when went through the process of building the truck online in 2020 it showed them as an option. If they really are incompatible, does anyone know how difficult it would be to make them fit if even possible?! Much thanks!
