Will this dashboard cap fit without any modification?

Yes. It's designed to use your factory mounting points directly. Test-fit before final installation to confirm alignment with your specific dash configuration.

Does the blue finish need prep or paint before I install it?

No prep needed. The finish comes ready to install and matches the factory blue interior. If your dash has collected debris or sun damage, wipe the mounting surface clean before fitting.

What tools or hardware do I need to install this?

Installation hardware is not included with this cap. You'll use your existing factory fasteners and mounting hardware already in place on your dash. Basic hand tools are all you need for removal and reinstallation.
