Billet referes to machining a part from a large solid piece of material, usually metal. I may be wrong but, I don't think any one is making grill parts that way.04 SlingshotSSR said:
There are some shops that make chromed sheetmetal grill parts. They have been reviewed in past postings, and there are pictures in the gallery.
Tip, look for pictures, then search the forum for posts by that member.
