Inner wing mods?

[haynes]

Any ideas how much of the inner wing needs to be kept without needing brace bars, for the mot? I'm keeping the wings all welded on but want to give a bit more access. On the clutch side theres the large air intake hole which looks a bit crap.

I was thinking of at least creating large enough holes at the bottom to get a hand/arm through if needed. I'm sure ive seen the inner clutch side wing replaced with a perspex panel, would that get through an mot?
