The mesh is pre-set by the mount on these, so you'll either have it or not depending which way round mount is. Iirc the bottom screw is at the 6 o'clock/central position in the mount, and the top will be the offset one. If you still want someone to take a look i'm travelling down sunday afternoon to crawley if thats anywhere near you? The train will get me there about 18:00ish Sent from my HTC One M8s using Tapatalk
