Help! Got my car back from the bodyshop today & the fuel cap cable/plastic string is detached from the plastic post. Almost dropped the cap on the ground. I think they busted it at the bodyshop when they took the quarter panel off. Would someone take a look ath theirs & let me know how it's kept on? It looks like something got snapped off the top of the post. And it looks like it's supposed to be one piece, but I'm not sure. Maybe I can glue something on top of it to keep it from coming off easily... Any ideas?

Thanks in advance!
