Removing hood

[s3 bob]

I need a new rear screen and have been quoted £150 or £75 if I remove the hood myself.
Does anyone know how easy is it to remove (and refit) the rear hood section? Would the extra £75 be money well spent?

I've got the old version, but failed to find anything with a quick scan through. I'll have another look, ta.
Might have a go at re-rivetting those damn rattly hood stays at the same time. They've only been annoying me for three years.....
