A fellow member of the site was the person who found this info—FBRKR. All the thanks should go to that person. I ordered mine from “Fox Powersports”. They order on a daily basis from BRP—so it took a week to arrive. Install was easy—had to remove the mount in order to place it properly. Best of luck to you!
