Like I mentioned it was the updated cover,#5433542 that replaced the #5431961 cover that was used on most models back then. It's shape is very similar to the original but it's a hardened cover not subject to warping or collapsing as bad as the first one. The part number should be stamped inside. The later covers were the bulbous type that you'd have to change out your air duct or modify it to fit that big exhaust duct hole. Don't freak because if was going to warp,this used one would probably have done it by now.. Here's the big one that would work,but the screw holes didn't match up entirely with your backing plate,plus you'd have to make an adapter to transition down to your smaller outlet duct.

Gotta be careful with some of those sellers on ebay.There's plenty more covers out there.Just let the sellers know that you know the difference between the two numbers and not try to pawn another one off on you. It's only listed on Polaris Parts as having an updated number.
