ISOFIX Mounting Kit - 2018 Mk3.5

[jimb1177]

Hi, I've got a 2018 Mk3.5 Focus and have only recently discovered it doesn't have ISOFIX mounts installed as standard. But I have seen this ISOFIX mounting kit is available from a few places online (mainly overseas it looks like). Despite this being a genuine Ford part (part number 1357238), I've called 2 dealerships, and Ford Australia directly, and I may as well have been speaking another language - none of them had a clue what I was talking about.

I've found this really useful video that clearly explains installing it in a Mk2/Mk2.5. I've got as far as removing my back seats, and as far as I can tell, the mounting points in the video look identical in my car. Some photos here.

My problem is, I can only find the ISOFIX kits listed for Mk2 - nothing comes up when I search for Mk3. Does anyone know if this would this still be compatible, or any other reason why this might not work? I'd be surprised if the mounting points moved between the Mk2 and Mk3, but obviously can't be certain. Also, I assume a mounting kit ordered from the UK, would still work with an Australian Focus? If anyone has any experience with this, I'd really appreciate it.
