I think you can keep your stock brush guard, but my experience is with a P1K1000-LE.
I bought a KFI mount, which is inverted to have the cable spool over the top. Inverted reduces the angle through the fairlead rollers to reduce wear on the wire/rope. The fairlead bolts through the brush guard to a backplate that comes with the mount.
It was very easy to install, did it all solo, and I didn't have any trouble putting the brushguard back on myself. There are stories on other threads where people struggled to get the brush guards back on.

This is it. The fairlead bolted onto the stock brushguard and you can easily reach the freewheel release around the left side. You can also see the snowplow mount underneath. Most of my use has been to lift the plow, but I've recovered a stuck SxS and it was good to have the 4,500# pull. We anchored my machine and dragged a razor up hill. (Eternal truth: Honda tows Polaris).
I found the link to the mount and it looks like this will cover you. It was very easy to install.
