How do you fix headlight of 1991 Pontiac firebird?

Problems with your headlights are usually associated with the headlight gears becoming stripped or the "pucks" underneath the gear have been ground to powder. Check out these links to purchase replacement headlight gears. These gears are made from CNC milled stock and work very well; I purchased and installed them on my 91 Firebird. Note: if you purchase from Rodney Dickman, he includes the Gear, Delrin Bushings (i.e. pucks), Gasket, and Silcone Grease.
