Was gonna try and post a scanned page from haynes manual but can't figure out how to do it.
But basically what it says is to remove the buld, detach a retaining clip from the upper adjusting screw, then squeeze the locking tabs on the two lower adjusting screws while pulling outward on assembly. To put in, align the screws with the holes and push in until the locking tabs engage.
