I added some model detail for you Aussi.
As for your question, like I said over on OzSpyderRyders in my reply to you there (as Old 85

) there was a time when we could get an A/mkt Hinge Reinforcement, altho I don't know if anyone is still making/selling them. And Stu gave you the applicable OEM part numbers & Oz prices back there too. :thumbup:
Just typing 'hinge' into the Search field (Top Right of the page) & selecting 'Search Titles Only' in the drop down list before submitting the search reveals that there are quite a few threads here on the Forum about this, here's one that might help a bit:

So apart from doing that search & some reading, unless someone here knows of anyone still making/selling those A/mkt Hinge Support parts, then as I said in that post, your best bet might be to do some DIY work to support & strengthen the area the hinge connects to, both on the bike side
AND on the lid side of the pannier - I know that some have used fibreglass to do this; others have used plasti-bond or similar on the inside bits where you can't see it; and then there are a few who've used longer/wider pieces of metal screwed/bolted thru the outer panels to spread the load of the lid itself & that each open/shut hinge movement applies.... and then try not to ever fill it so full that you need to jam it shut!
If no-one else has the other info mentioned and it gets that far, it'll come down to your choice of trying to do an invisible repair; doing an obvious repair; or buying/replacing all the damaged bits as appropriate. Stu's prices on those items on the other Forum are usually pretty good for Oz, but he is in Adelaide SA so P&H wouldn't be cheap - hopefully there's someone like him nearby, or at least a dealer who can help if you decide to go down that path. MickQ (who's in FNQ btw, up beyond Cairns towards Atherton.

) may be able to help you with some more local info on that sorta thing. :dontknow:
Over to you. Good Luck! :cheers:
