Where to find a Rover 25 relay switch

Hello, i have a rover 25 with a drivers side electric window refusing to work, before i start looking at the regulator or motor i'd like to replace the window relay which sits high up above the fuse box above the driver pedals.Unfortunately there doesn't seem to be a lot of rover 25's in my local scap yards and the only relay i managed to find is the wrong one.Does anyone know where a replacement relay may be found.many thanks
