Last year I removed the seats from our 2004 Thunder so they could be redone. I removed them by unbolting them from the floor pedestal and all. The others were right, they are HEAVY! When I installed them, I separated them from the pedestal and installed the pedestal first then the seat. Much easier. Before you do it that way you must move the seat either back or forward to get to that set of bolts, then move it the other way to get the remaining bolts. If I ever do it again I will leave the pedestal mounted and just remove the seat. Marty
