I've got a set, along with the bed hitch frame. I had both in kits in my hands when I purchased it and the only difference I could tell was there was a little less (1/2") offset from the frame mounting surface to the bag mounting surface. I'm guessing that was due to the thickness of the hitch rails one the frame. That and the fact the non hitch mount already had holes drilled into it and the hitch mount had to either be drilled or welded once it was positioned on the side of the frame. Since you don't have a bed hitch, you'll have plenty of room to position it on the frame to get it just right. I had to do some grinding/trimming to make mine perfect.
