Perfect thanks. That is the exact same part, showing the exact same part number, as in my original post. i’m guessing that bronco was manufactured/delivered towards the end of 2024.

that is for the hardtop
That eBay link (BA) is for the soft top. :(


softtops are -BA, hardtops are -CA, that's the point

I only care about the parts number up to a point. I’ve spent hours on this little project and can confirm, since I have now bought the trim inserts and installed them, that the trim insert pieces in my original picture fit the hardtops correctly. I recognize the confusion with the part numbers, but I bought my parts off eBay based primarily on the picture of the part compared to the dozens and dozens of Internet pictures of Broncos that I looked at. Specifically, there are many many videos on the Internet of people taking their hard tops off. If you watch enough of them, you can identify that at some point in 2024 or 2025, Ford started including this trim insert. So I’ll leave the debate over what the correct part number is to other people, and otherwise hopefully my post is helpful.

the main idea behind us chasing part numbers instead of engineering numbers stamped to the part (I know that sounds ridiculous) is that we can order them directly from a dealer, no trust to ebay

@Ducati1098 Can you verify the part number for 2-door Broncos?

Those engineering numbers come up as invalid, which happens sometimes. The cross reference thing doesn’t always work.

According to the parts catalog, here is what it shows for 2 door SPNs:

Well, yes, of course I know that. The answer there is just to go to a dealer with any vin off the lot and they can get you the part number. Or if someone has expertise like Ducati they can share the part number. I was able to do it quickly and easily and cheaply without 100% certainty on the part number. I just wanted to alert the community to this new trim piece that I suspect a lot of people don’t have and might want. I did not spend the extra time to confirm the part number because I figured that that would get figured out through the thread.

interesting. Ducati, this parts diagram does not show the part in question. It is a trim insert that would fit inside the trim piece having number 20554B in the diagram. InfiniteDomain posted a picture above of his two door and it shows the insert.

Did some highway driving today and I can confirm at least subjectively it has a noticeable effect on reducing interior noise from the back. That however, does make me realize how noisy the front of the bronco roof is. 🤔
