Slightly off: Can you link me to this mod? I can't seem to find it. On: What were you expecting? It works. No need to create a thread just for this. I guess it's fine, just not needed.
You should just be able to search for “6.7L diesel” in the new mod repository. EDIT: I found a link pretty easily https://www.beamng.com/resources/6-0l-and-6-7l-diesel-for-d-series.2525/
Actually I did search for it. I even found it, but when I clicked it it said I don't have permission to view it. That's when I asked for help. Oddly enough I can view it and install it just fine now.
