Those look like Wedge or Planted seat brackets. I had horrible luck with the fitment of the Wedge brackets. Either way, both brackets will put your seat about as low as possible in these trucks.
Also, the sliders are pretty much all the same height. If you wanted to mount the seat directly to the brackets in a fixed position, you would gain an inch or so.
Other seats may have a thinner bottom cushion, which would also gain you some room.
