I installed these on my son's 2003 Mustang. The driver's side fit great. The passenger side did not. I was able to finally get it into place but there was alot of up and down play and a gap on the side. The lights would bounce when hitting a bump. I pulled them back out and noticed that the header panel of the car had some stress on the passenger side and replaced it. Headlights still did not fit. My son then got pulled over by the police and was issued a ticket for faulty equipment due to them bouncing. I sent 2 separate emails into Anzo and never received a response back. When I called them, they said that there was not anything they could do as I purchased them from Amazon. I cannot request replacments from Amazon as I am over my period of time for being able to return them to get replacments. At this point I do not even want replacements if they are going to give me the same problem. I am out over $250. I wedged a couple small pieces of pliable foam under the lights to keep them from bouncing. Now I have worn 2 grooves into the top of the plastic lenses from where they still move slightly and the hood is cutting into them. I am out over $250.
