Do I need to paint this before installing?

No—it'll work as-is if you want a primed interior look. Most people sand the primer lightly and apply their chosen color to match the door panel or keep it black. Either way, install first, then paint if you want.

Will this bolt straight onto my door without modifications?

Yes. This handle uses factory mounting points, so no drilling or frame changes are needed. Just line it up with the existing holes and secure it down.

What fasteners do I need to mount this?

Mounting hardware is not included with this handle. Check your vehicle's service manual or test-fit the handle first to confirm bolt size and type before buying fasteners separately.
