Ok I fixed the loose headlight this morning. As some eluded to there is a long thin threaded rod that sticks out from the back of the headlight housings. There is a square socket fitting on the end of the rod, at the headlight end, the rod/bolt is threaded and there is a nut on the end. This nut has to be tightened if it loosens up or else there is play from the space between the nut and the casing and the headlight can move forward and backward several inches.
take a 7/8 socket(forget exact size i used) and slide it over the rod and the nut on the end, hold the end of the rod with a vise grip on the squared sides of the rod and turn the socket by hand to snug the nut against the housing. Spray with WD-40 first so it moves easy.
Takes all of 5 minutes to do.
Car is legal again, just clicked to 177,000 miles and runs awesome, passed emmissions without an oil change or tune up-just new aircleaner. This car is saving me a lot of money
