Headlight Help: Any would be greatly appreciated.
 

I own a 1996 ThunderBird LX, 4.6L V8, and I am looking to spruce up my headlights. I installed a HID kit a little over a year ago, and am in love with them. But I am wanting to take them one step further. I am looking for measurements so I can install LED Halo Rings.

I have called around, and I cannot find any broken or used headlight assemblies so I can measure it myself. And I cannot disassemble my current headlight assembly just for the measurements, as I need them in once piece currently. So I am here to ask for help, since I am not completely car savvy. I do have the measurements that are listed on the site I am looking at, so here they are: 2.36"(60mm), 2.75"(70mm), 3.15"(80mm), 3.54"(90mm), 3.94"(100mm), 4.33"(110mm), 4.72"(120mm). I have a feeling that this is only in the 2-3" range, but I know I could easily be wrong.

And here is the site itself: Lumen® - PlaZma LED Halo Rings

A friend of mine has the experience necessary to do this for me. But I will be watching/hands on so I can learn how to do this as well. If anyone can help me with figuring out the measurements, I would greatly appreciate it.

Thanks a bunch for even taking the time to take a gander at this!
