Hi, I just ordered on amazon this rack:

Item #2879717

Sportsman 570 / 450 H.O. Rear Rack Extender- Black | Polaris ATV Store

The polaris web page the fitment guide says it will fit my 2016 Sportstman 570 Touring SP, but found one comment from a user at amazon that says it wont fit.

Does anyone had already installed this rack?
I would hate to get that part shipped and find that doesn´t fit my atv.
