I emailed Dave and he emailed right back. He said he didn't sell the cuda grille parts but Metro, even though out of business, may have some leftover parts.
Dave also said that I have the Black Premier Grille which is prone to warpage in extreme heat. So it's really not a good grille to install and is not being produced.
So I think my best bet is to relinquish this grille to garage art. I would hate to fix it up and use or sell it and have it warp down the road.
The good thing is I got it with a huge e body parts stash so it's not a huge problem just a disappointment
