I believe this would fit into a 392 since the back cargo area is the same as other trims - not 100% sure about that but most likely. I have the Mopar leather seat option in my Sport S, but was still able to put this in.
I have a two door and took out the back seat, and put this one in. I think it is great not just because the fitment is dead on, but it also has a little “lip” around it that contains spills/items. Very tough, well made item!
