It is a very rigid piece once installed but can be easily shaped to conform to most any grille shell. Take this exquisite piece and make a stunning insert for your ride! We own the tooling used to make this part and will give wholesale pricing in quantities of 10 or more. Here is some info shared by a satisfied customer who was kind enough to share his knowledge.
The easy way to install is make a cardboard template, then hold it onto the grill with squeeze clamps. Then cut the mesh around the cardboard with a thin cutoff blade, like in a 4 1/2 angle grinder, (I used a Dewalt) Just go slow and use eye protection. Forming it is best done on a flat surface like a table, pushing it down on the edge of the table to shape. Most Chevy grill shells have threaded inserts.
Then all you have to do was enlarge a few existing holes in the mesh with a Dremel tool, using an 1/8 carbide bit (the stainless mesh didn't like my small abrasive 1/8'' bit). My grill shell had 6 factory, threaded inserts and with small ss screws and washers it was a breeze. I also drilled 2 extra holes in the bottom, that's not seen very much, to hold the bottom of the grill in. You also need to use lock tight on the screws, because if you tighten them down very much you could crush the mesh, and it might show on the exposed part of the insert. Besides, you don't want the screws to vibrate out later.When You suggested an adhesive and that should work too.
