Will this bolt straight into my door without new hardware?

Yes. This uses factory mounting points on your door panel. Check the existing fastener holes before install to confirm they're clean and accessible.

Do I need to remove the door panel to install this?

You'll need to remove the interior door panel trim to access the mounting points. It's a straightforward panel removal — standard screwdriver and panel tools work fine.

Is this a single handle or a pair?

This is the right rear door handle only. If you need the left side or handles for other doors, order those separately.
