675 Instrument clock cover not fitting?

Hi all!

I have a 2010 Street Triple 675R, I had a flysheild on for a while but I wanted a change so took it off to replace with the back cover I had (with gasket), but it just doesn't fit at all, it seems like it is from a different model? its not watertight at all. I am the 3rd owner so I am not sure if previous owners had this issue, but why was it with the bike in the first place? its a genuine triumph part. I'll post some pictures of it. has anyone else had this problem? or is there a way to check the exact part number?

can you help

 

I finally got some time to myself to take some pics! Have a look and let me know what you think

 

Thanks for the help guys.

I've been emailing the local triumph dealer about this issue and they seem to think I have the correct part (showed him all the numbers on the cluster and cover), his advise was just to push it in place but I showed him pictures which then made him say 'Oh yes I see what you are talking about'. Anyway seems like they have changed the panel type/number over the years and its just been misinterpreted. I was going to take it to the dealer today but the weather was a load of crap, raining here all day in London, so will have to take it to them a day after work. Will keep you guys posted....
