Hi all, At the top of each of my lift poles, they sit in a nook that has two threaded posts. Not all of the posts have nuts on them, and the ones that do are smaller than the opening and there are no washers, so the roof is not secured other than by the tenting. I have included a picture for reference. I got some nylon nuts to replace the missing nuts. Should there be washers in there also to secure the roof more? Thanks!
