Long shot but may as well try

Hi folks, new to the forum, had an explorer for the last three years but just changed to a trophy. I managed to get a trophy tank bag but the front fastening bit and the rubber part is awol. I realise this is a real long shot but just checking if anyone has any lying around unused !!!! Or any ideas for a workarounds seems a shame not to try something.
Anyway nothing ventured nothing gained as they say. Thanks guys
