I installed UTV Inc seat bases but cannot get the seats to latch. I had them on stock seats and they were very difficult to latch, but still possible. Now with these aftermarket seats, I can’t get them to latch at all. Anyone else had this problem?? Pics show driver seat with UTV Inc bases. Pass side is stock bases with sliders removed. When you push down on the seat, it clicks and sounds like it’s latched, but I can pull the seat right back up.
