I am not sure how they mount their seat. I found that when I placed my seat in the factory mount I felt like I was sliding off the seat. Also all together it raised the seat about 3 inches plus the seat was tilted forward. I found the lowest possible height I could based off the fuel tank and propped a level on the tank at that height. I then cut out my hinge arms using the factory bracket as a rough guide. I then found some 1 3/4 steel tubing with 1/8 wall and found the proper length minus the rubber bumper from the original springs. The cross bar the springs sit on has a slight angle to it so I cut the tubing the proper length and angle (welded the angle side to new bracket) I also had to shim the bumper so they wouldn't fall out of the tubing. I then took some steel plate and welded together for my base plate and welded the pivot arms and tubing to the plate. I also used some angle iron to fabricate a bracket for the locking mechanism so the seat wouldn't flop forward if it ever rolled over. I also ditched the factory seat slider because the seat I bought had a slider on it. Using the Grammer seat, slider, lateral disconnect and my bracket only raised the seat 1/2 an inch. Here are some pictures.
