I gotta get a set of these for my 05 Mustang GT. Looks like they are not exactly street legal for night driving but they are easily removed as needed. I dont see how it would be a problem covering the front fog lights on a GT.
I really like the vintage feel of this. I think you could make this from newer items and then distress to look older. The off center dim light is a nice touch to make it look older, less "perfect". Vintage auto headlight lens lamp by Joy Price
