To clear the lock mechanism and prevent binding we suggest a 1/2-inch-tall steel or aluminum spacer (NOT INCLUDED) for clearance between the seat and sliders. This provides a 2-inch overall height to the assembly, something to factor in with your floor mount and seat base height to determine your final seat height. Alternatively, our Universal Seat Mounting Frame and Slider Kit may be your best option, as it includes everything to fabricate a custom seat mounting solution, so be sure to check that kit out as well. Whichever way you decide to mount these, adding a set of our Universal seat sliders will make the ride much more enjoyable! here
