Some models do need an adaptor plate

Short or CanAm BRP extension : Many BRP models need the short extension plate to extend the top mounting bracket to reach the rear rack. The plate can also be used where there is a special need to gain extra room between the the rear rack and the Quadbar. Note that this can only be used (and useful) when the tow bar /hitch is also protruding out, close to the line of the rear rack.
