I'll have lights and grills available very soon as a package. I had the grills only available in the past, but pulled the sale of those individually as I wanted to offer them as a "package", and I also have fewer grills left vs lights. I started making the grills about 5 years ago.
New Hella 118 Fog and Driving lights coming soon from Auto Foreign
My old thread on grills:
http://www.early911sregistry.org/forums/showthread.php?70789-LWB-TTG-horn-grills-done&highlight=horn+grills
I made both SWB and LWB horn grills for fog lights.
Side note: In 1973 if the car came from the factory with horn grill mount fogs then you got chrome grills. If you went back into the dealership after you bought the car and said "hey, I want horn grill fog/driving lights", they would pull a package out of the parts dept that had all the things you need; grills, lights, switch, wiring, brackets etc. BUT, the grills were the black plastic ones with a "clipped" center bar (the factor offered them clipped, they weren't molded).
In answering dg567, yes, if you grind out "about" two inches of the center bar (a chrome one) you can put lights into your car, you can simply "clip" a black one as they are plastic.
The lights and grills I made will also be available soon from our "host" here.
Cheers,
Eric
PS. On a real side note, there was a provision to mount round fog lights to the 1973 "S" spolier. There was a special bracket that fit at the bottom of the front spolier/bumper and accomodated the lights. Somewhere on Pelican there are pictures of a 1973 RS (real) in a Violet color with these lights mounted (and on the kardex for the car).
