I fitted the front fenders and they fit perfectly. Easy installation with existing screws and holes. I used a clamp and an extra screw inside to hold the existing part a bit tighter. The rear ones fit and mate with the existing holes, but there wasn't a convenient place to put the extra clamp and screw to hold the existing part in place. The gap is decent, but I don't think anything will collect there. It's just that visually it's not noticeable through the truck and they look nice. I'll keep them enabled and if the disruption gives me problems I'll update them! In general, everything is fine with the equipment.
