I have a 2013 base mustang that the previous owner or shop has ruined the adjusting assembly. These headlamp assy are VERY expensive. Is it possible to just get the part that adjusts the height and not need to spend $800 on a new assy?

 

A Ford dealership parts dept should be able to answer that for you. Dealer item.

 

I do not believe so, the adjuster is internal to the headlight.
