you have a good seat there, could i make a suggestion as i have spent a long time working out seat plans and its always the rail that lets the seats down on any highseat. if you lowered your front bolt that holds the rail and then on the back upright you drilled a series of holes you would have an adjustable rail but you would need to make the side rails longer for extra holes as well this would mean you could take your seats to different locations if needed just a thaught ,great seat,wayne
