Now I gotta go back and reinstall mine. I put them over the center trim. And they fit just fine. They may have been tweaked some over time but they fit over the center trim just fine. My mirror mount is "T" shaped and covers the top at the headliner gap rather well. So since it would mean fitting into the center trim, PITA. I think on second thought, I will leave it alone. I found mine in one of the boxes of parts the PO gave me when the truck was bought. So when they fit on the outside of the center trim I thought it was how they went.
