seems like a bad design. i can see getting them off with a pair of needle nose pliers. putting them back seems like it would be a lot harder. is there a downside to cutting into the fiberglass on the inside for better access?
For me I've never had a problem getting them back on. Its tight but was just able to prop the wingnut until it took a thread or two. Then just hold the wingnut with the needle nose again. You want a real pita try to get your side panel off haha
