Turns out on my GU Patrol the spacer kit actually wasn’t required, but I was super happy with the quality of the table slide and all thr fixtures. If I had to pick on one thing, it would be that where the table hits the pinchweld at the rear of the slide, the rain goes into that pinch weld and because it’s mild steel inside the pinchweld, it has rusted within a month of being on the car and dripped rusty water onto the stainless slide and down onto the car roof. I still absolutely love this product though! There’ll be an easy fix! Thank you Kaon!
