Very explicit, thanks Terry.
I am still wondering if the whole pedal assembly can be moved across to the right even more, so that the accelerator pedal is a few mm from the side panel, so that there could be enough room alongside the clutch to rest a left foot? It will be tight, but may be doable. Sadly your picture just cuts out the right side of the accelerator pedal, so the distance from the side can't be seen, although it looks as if it is across pretty well all the way.
If this is so, I am certain that the accelerator pedal can be moved slightly closer to the brake pedal, and still be operable, so the assembly can be moved to the right some more, thus releasing a little more room on the left for the clutch foot to slide down alongside the clutch pedal.
I can see a few hours in the garage coming up.
