Spent about 1/2 hour this evening starting to knock up some brackets for the induction kit cover :
One picks up on an existing mounting.
One will clamp between the heatshield and inner wing, and will be prevented from moving up by the wing edge.
One will require a small pair of self-tapers above the filter.
They will all get 3mm tapped holes drilled in them for the cover to be screwed down onto.
I will de-burr, round the edges and flic some paint over them tomorrow.
