The Honda front mat set includes the two plastic clips for the passenger side, at least on my rubber mat set. You have to cut out a small square in the carpet around the existing slits in the carpet using a Stanley knife. Instructions were not supplied with the Honda front rubber mat set I purchased but the vendor emailed me the installation PDF document. The rear rubber mat set also requires you to cut away some rubber on one side, as the driver’s seat lower seat belt anchor housing is a different shape to the passenger side and this would swap to the other front seat on left hand drive vehicles, allowing one rear mat set to be manufactured for use in both left and right hand drive vehicles.
