Got some nice sheet metal from a local steel stockholders so will be cutting and welding that onto the hatch to fill the two holes!
Oh and a folded piece across the top to replace the plastic lip.
Next problem is going to be a hatch release button.
May be able to use the old one turned around 180 degrees but that depends how that positions the rod attachment!
Have thought of trying a Passat boot release as that would suit but again depends on the rod attachment!
