Does this come with mounting hardware?

Hardware for attachment to the door panel is not confirmed in this listing. Bring fasteners that match your existing door panel configuration, or plan to reuse hardware from the original handle if it's salvageable.

Can I install this myself?

Yes. This handle mounts at factory points with basic hand tools—no drilling or door panel modification needed. You'll need to remove the interior door panel trim to access the mounting bolts.

What if my original handle is cracked but the cover is still good?

This is a complete assembly, so you're replacing both the handle and cover together. If your cover is still serviceable, you'll have a spare trim piece left over.
