You can get them here at Stage 3. These are for the XL/XLT only, the Lariat Grille lights are different and are these lights. They're super easy to instal and there's a YouTube instal video on the page.
I installed the 4 light kit in my 2022 XLT and the lights are great but the wire routing to the drivers side marker lights was a PITA. The install video and my battery area was totally different. Lights screwed in place was easy. Routing the wired not fun. Looks great tho!
There is a little bit of fitment but nothing too difficult. Yes the center comes out.
I believe there is some post here on it.. Once you have the back of the grille you will see it clearer,
