I buy and use KFI mounting plates. I will be adding a warn pro vantage 2500s to my '05 trx500fm, and the KFI mounting plate to it in the future. I looked the mounting plate up on KFI's web site, and at first on the page, it did not list the plate for my year ?, but when I clicked on the nearest year/make ?, it showed it on the list, sooo. do your homework !. I guess the reason they show every year but mine at first is because the front bumper changed from I-beam to tube bumpers on my model/year ?. but I did see they make a plate for it. KFI winch plates are a solid buy, I've bought them for every warn winch I have installed on every atv i've owned and sold, not one problem. although !!!, I will say, they should have studied the mounting bolts ( u-bolts ) as to where they bolt to the frame/bumpers ?, because I've ran into some tricky spots to get them to bolt up..lol.
