Will this bolt straight to my grille opening, or does it need custom mounting brackets?

It's designed as a bolt-on piece scaled for early 32 grille openings. Verify mounting points on your specific grille before final purchase—test-fit against your opening to confirm alignment.

Does stainless steel need to be polished out of the box, or does it ship ready to install?

Stainless arrives with a brushed finish. You can install as-is or polish it to a mirror shine depending on your build aesthetic. Either way, it won't rust or require primer.

What hardware comes with it for mounting?

Mounting hardware is not included with the guard itself. Plan to source stainless fasteners matching your grille's existing bolt pattern—this keeps the assembly corrosion-free long-term.
