Ok I have 1994 disco it has the oblong headlights which are held in at the top with plastic adjuster screws, these plastic screws are held in place through the metal surround, they then screw onto the lamp housing and you can adjust aim by screwing the plastic screws in or out a little. My problem is the plastic screw threads have now gone so the headlight is now free on that side and rattles about, does anyone know of a fix for this problem.
