im trying to find some boat guide posts for the rack on top of my xj. i have a small 11ft. jon boat that is small and light enough that i can throw it up there myself but had a few times where i almost lost it off the side and i dont really want to scrape the whole side up or lose a mirror. if anyone knows where i could find some that would be awesome, im not even sure anything like this is made. not really looking for anything expensive, just something that works and could be removable. thanks.
