I had an old tie down laying around so I cut two pieces about four inches long and folded them double. Then I drlled a hole in the ends and using the same bolt that you did I bolted them under the rack. Now I have a 2 inch nylon loop hanging out under the rack for bungee cords. Very soft and no chance of cutting the seat or a passenger. Just an idea!Not wanting to use the rack for a front bungi cord attachment point, I made up a 10 guage plate with a steel bushing welded to the side. No problems touching a passengers leg. Very handy for attaching a duffle bag to the seat.
