Matt, the brackets are the stock ones that came with the original seat. If you look closely, you'll see that I placed 1" PVC "spacers" between the board and the brackets. I cut a couple different length spacers and took the boat to the pond to see just how low or high I wanted the seat. Lower is usually better (stable), but with the hull mods, I was able to remove the spacers all together and bring the seat up higher and still have good stability. And that helps ALOT on your lower back and knees when youre fishing out of the boat all day!
