That would be me.
But the view is that there is no yellow Grommet on the Rt passenger fire wall of a LHD in the US.
Ironic, considering that there would be a matching punch-out which would mirror a RHD. But I'll take Andrew's and Matthews word for it. I did not want to look forward to a 20 hr repair as the gentleman with the M5 did. I have an M6.
Also. Noted your endoscope camera picture. How did you get it in above? By any chance would water leak in from there? Seeing all the Yellow Grommet pictures and the plate covering it, some of you captured a rim of galvanized metal just above it -which made me wonder- if that would have also contributed the water intrusion in to the space as well as some pine needles and dirt.
