Do these panels come with mounting fasteners?

Panels only — fasteners not included. You'll need to source 10mm bolts or screws based on your mounting surface and preference.

What should I do to prepare these for paint?

Clean the surface thoroughly, then sand and prime according to your paint system. The bare finish accepts standard automotive primers and topcoats.

Will these fit my specific bumper setup?

Universal design means they're not locked to one vehicle. Test-fit first to confirm the mounting holes align with your bumper structure before final assembly.
