Wanted, Drivers door window clips for 2000reg K11

Hi, I'm new to this site so please excuse me if this is not in the correct forum. We have had a W reg Micra Celebration for going on 20 years and its been as sound as a pound. However in its dotage it has a problem with its drivers side door window. The regulator is fine its the two little plastic clips that connect the window glass to the metal rail on the regulator. They probably only cost pennies to make but are only available new glued to the window glass at £80 upwards. Lots of second hand windows come minus these clips. I've spent hours trying to track something down but as yet to no avail. Can anyone here help me find some?
