hi i will be using a billet bar grill on my build because of needed extra room up front for air to air cooler. I would also like to get a small billet grill for the GMC hood. Does any one know where i could get the hood one or will i have to make one? Thanks Denis

I'm not quite following what you are asking.

Do you mean that you have a GMC that you want to put a billet grill in?" or are you wanting to convert a Chevy to GMC style hood?

I've got a notion that you are going to be on your own making one. If it were me I'd do a mockup using something like Masonite or MFD that was closest to the desired thickness that I got at Lowes or Home Depot or my favorite local lumber yard so I had the exact shape of the bars as I wanted them and take the pattern to a shop that can waterjet it out of aluminum. You can throw a way a lot of mistakes from a 15.00 4x8 sheet of that stuff and not feel bad.

One thing to remember is that those (and Chevy) grill openings taper from bottom to top slightly and the bars will have to be graduated in length accordingly to be right.

The other way is a lot of cutting and fitting with aluminum flat bar. Or get square aluminum bar stock and cut and shape the bars. This chart gives the ability to bend of different alloys. https://www.clintonaluminum.com/whic...oy-bends-best/

That would give you the alloy to look for which probably would be 3003 or 5052 as a lot of the others don't bend well. I'm not finding either in square stock though. Most of the square stock is too hard for bending well.

I've never seen one and would imagine you will end up having to make it. I just don't think there is enough market for them for anyone to want to produce them.

If you are buying the main grill from the outfit that actually makes them you might ask if they have bars available that match the main grill. They may even have a damaged grill that they can cut a section out of that you can work on to fit your opening.
