Do I need any fasteners or adhesive to install this?

This assembly mounts at factory door attachment points — you'll use your vehicle's existing hardware. Have your service manual or a shop manual nearby to confirm the exact fastener locations and any trim removal sequence.

Will this fit flush with my door panel, or does it need adjustment?

It's designed for the factory mounting location, so it should sit flush once bolted down. Test-fit before you fully tighten everything to make sure the cover panel aligns with surrounding trim.

Can I return this if it doesn't match my interior color?

Check the interior photos on the listing and confirm the color matches your door panel before purchasing — that's your best move. Standard return window applies if there's a defect, but color mismatch is a fit issue on your end.
