Will these handles work with my factory interior trim and switches?

Yes — these are direct bolt-on replacements designed to mount at existing factory holes. Panel and window switches remain unchanged.

Do the handles come pre-assembled or do I need to prep anything before install?

They arrive ready to install. No painting, priming, or assembly required — just unbolt the old handles and bolt these on.

What hardware comes in the box to mount these?

The handles ship as a pair. Verify your vehicle's existing fastener condition before installation — reuse factory hardware when possible, or grab new bolts from your local hardware store if needed.
