Fender Flares

I am wanting to replace the stock fender flares to some that are wider to give a bit more protection from crap being thrown up from the tires.

I know one of the other 900 models has wider flares that fit right on my 900 50" Trail, but I do not know which for sure.

Has anybody replaced theirs with the wider flares and from which model did they come from so I can properly source the PN for them.

Thanks
