Anybody out there having issues with their stock seats? I've had all the screws holding the seat to the frame back out and when I go to tighten them, they're stripped out. An obvious fix would be to put the next size up screw in, but is there a better fix? I would love to put some aftermarket seats in it, but I don't know if that's going to fix my problem. Plus, I like the adjustability of the factory seat frames. My wife is only 4'9", so her seating preference is a bit different than mine. LOL! Also, I'm wanting to add some harnesses. Do they work very well with the factory seats?
