TL50 Grill 101 from my experience...
TL grill came in two pieces; Ford charged something like $90 for the genuine plastic surround, but they stung you $1200 for the woven stainless mesh.
The 4 top tangs scrivet directly to the radiator support panel - IIRC two new holes need to b drilled for the outer two TL top support tabs.
Top of mesh was welded with a hidden steel bar that was riveted to top edge of plastic surround. The bottom was attached to the bumper by the 4 lugs you can see in the pic above. Those lugs were part of the mesh piece - a bar is welded to the folded bottom edge of the mesh that has those 4 metal rods, which then poke through the surround & into holes in bumper. There's minimal spots of tape around those lugs to allow some movement in case of accident.
If the ones on ebay don't have those 4 holes, they're not genuine NOS, they're aftermarket copies.
If they are genuine, absolutely buy it ASAP. The exact mesh is easy to source for around $100
