You can leave it in and not use it or go to dealer and have it removed like I did. When I had it done they said they had all the parts. Guess what they didn't parts not available until end Feb 2027.
Those are what comes on it so they are painted like that from factory. Maybe see if you can find one in wreckers would be cheaper than getting them from dealer or maybe see if they can wrap them. Wraps are pretty durable we had a couple of our fire trucks done in a complete wrap.
