I was planning to start a thread on my conversion when it was 100% complete (I haven't made the lexan covers yet), but as an intro, I would first and foremost say that I would NOT do this on a street car. It completely changes the character of the car, and it is a TON of work (took me a solid month). Having said that, I went with the approach AJ Hartman Racing used on Pablo Crespo's car, in that I removed all the hardware for the standard lights, bolted the new ones (Hella bi-halogens) to brackets attached to the bulkhead in the back of the headlight opening in the fender, and fabricated curved buckets out of aluminum flashing, which I then painted black. I then plan to make the covers myself, heating them up in the oven with a weight in they center to give them some curvature to match that of the fenders. Here are a couple of pictures; the car is still up on jack stands in my garage, so I can't get far enough away from it to get a good shot of both headlights:
So, it's basically the light-in-a-hole approach taken by many modern manufacturers. I think the look is passable for a track car (especially once I get the curved covers in place), but I much prefer the look of the stock headlights. Also, warning to anyone travelling in the Austin area, particularly at night: I will be using my headlights VERY sparingly, as I haven't figured out a way to change the bulbs without completely dismantling the entire assembly, which will take many hours. <img src="/forum/images/smilies/968/mad.gif" class="smilie" alt="" /> <img src="/forum/images/smilies/968/ohmy.png" class="smilie" alt="" />
