Do these caps work on both my Fleetside and Styleside bed options?

Yes. These are engineered to fit both configurations without any modification or fitment adjustments needed.

What mounting hardware do I need for installation?

The caps mount at your factory bed rail attachment points. Verify your existing hardware is in good condition; replacement fasteners are standard automotive bolts available at any hardware store if needed.

Can I paint these before or after installation?

Install first, then paint. This protects threads and fastener areas from overspray and ensures a seamless finish once mounted to your bed.
