I've loads of screws and four sets of spare skirts, I've made my own fairing walkway and will do the cylinder cover when I get to a satisfactory point on the A3.
Your welcome to any spare skirts you think you need, screws too as like above all the ones that attach the skirts are going spare. Beware the screws, they're a course pitch sort of self tapper and if your using them in and out or leave them in tight for long periods the Mazak tightens up and then you sheer the heads off. Sometimes they sheer off when tightening the first time, the screw material isn't really very good in all hnesty.
I may end up drilling all mine and tapping a machine thread instead, M2 or M3 if the casting will take it.
