Kind of looks like the E&G Classics grills for 90's Cadillacs.
347thunder has one of those on his car
LOL, I have one in a box.
These things need a ton of fabrication to work. It's laughable that the add says "This grille kit installs with bolts and brackets (included with grille kit) and requires cutting the factory grille.". They may only be an email away to walk you through it, but they aren't going to conjure up mounting points for those brackets with an email.
If you are good at fiberglass and have a nice grill shell you may potentially ruin, have at it!
I have about 10 hours in mine and I went back to the stock painted grille I might just sell mine,
