I built my own. You’ll need flat piece of metal about a 1/8” thick And 2 1/4” wide. I installed 2 rubber seat mounts(from a 3 wheeler frame I had sitting around) by drilling holes and pressing them in the holes. For the latch I cut a slot and welded (I’m a crappy welder but it held) in a nail. Works great And has lasted at least 2 years now. A replacement was gonna cost about $100...this cost about $5 and about an hour of time.I'm in search of the bar that goes across the battery to lock the seat in place for a 98' honda foreman 450 if someone could guide me in the right direction for that part I would greatly appreciate it thank you
