Looks like the bolt/ large washer is between the blue mark on the steering column and the end of the ash frame?
I wonder if just removing the leather covered panel underneath might give enough acces to the nut? Maybe no need to remove the dash. A replacement nyloc nut would be good to use. Be careful with the socket head area on the pillar outside. Potential to nick the paint so mask the area first.
Any info for removal of the panel?
