Do I need fasteners to install this, or does it come with hardware?

The bracket ships without fasteners. You'll need to source bolts and washers to match your factory mounting points — check your Stinger's service manual or test-fit the bracket first to confirm size and thread pitch.

Will this work with my front bumper as-is, or do I need to modify anything?

This bracket mounts at factory points with zero modifications to the bumper. Just verify the mounting holes align before committing fasteners — no cutting, drilling, or grinding required.

Can I paint this to match a custom bumper color?

The powder-coat finish is durable as-is, but if you want a different color, light sanding and a quality automotive paint will bond cleanly to the prepared surface. Prep the bracket like you would any metal part before painting.
