Sorry - bit of a strange description. The heater vent on the right hand side (drivers side as im in the UK) is missing its little plastic handle. The bit I push to move the vent about. The metal bit underneath is there so nothing is broken - simply the black plastic piece missing. All of the heater vents look to have the same piece on - they dont appear to be angles at all so any should do. Would anybody happen to have one of these?

Thanks
