Ijust replaced my cracked 93 KDX200 headlight shell with a "factory replacement" unit from Maier. I got it on, but was not impressed to say the least. The area where the headlight connects to the plastic did not resemble the factory shell at all. I had to mount a supplied L bracket to the plastic that hopefully will hold the light in place. The only other contact is the tiny adjustment screw, which I had to drill the hole for. The area at the top where it mounts to the speedo also is nothing like the factory set-up. There I had to also use supplied brackets and drill holes through the number plate. Bottom holes also had to be drilled. I don't know how much the factory plastic is, but I wish I would have at least checked on it before getting the Maier. If any of you are about to do this, you might consider a real factory replacement if available.
