Yes indeed, very hard to tell.
If you turn the steering to the right and look from the left side in the gap - you still can’t see anything?
Of course, all the parts are available 
Please don’t disassemble it yet, let’s talk first with Bill, maybe he has an alternative idea.
It can be quite tricky to get the plastic halves out of the frame because in many cases the Philips screw will be seized together with the claw nut which sits inside of the plastic.
If that happens, there will be no other chance than to destroy the plastic totally and pull it out in pieces (very nasty work).
