Hi Graham,
Congrats on the GSA - I'm sure it's going to seem a long week until Friday!
I don't think I did much in the way of documenting installing the AirFlow for the GS, but I did post about the process on another forum when I made one for my NC750X (see link below) This describes how I got the holes for the clamps in the right place which is absolutely critical as the rails on the back of the AirFlow which run through them will either not fit or be too tight if not accurately placed. You also need to decide how high to place the AirFlow on the base screen depending on how high you need it to go, taking into account adjustment on base screen plus additional adjustment on the AirFlow. I suspect they work better the more the two screens overlap, so although my Airflow clamps are positioned such that it can extend to about 150 mm above the base screen I generally have it set so that it only extends about 50 mm above the base screen, measured in the centre where the base screen dips. The base screen is about 490 mm tall measured in the middle and I have it set near the bottom of its adjustment as you can see in the picture.
I would say you need to be reasonably handy in DIY terms to do this. You have to cut two big holes for the clamps, and then two smaller holes on each side for the screws which hold all the parts of the clamps together, though you can mark up the position for these after a trial assembly from what I remember. Are you planning on replacing the stock GSA screen with something else and adding the AirFlow to that? I'm not sure if the material of the stock screen is as suitable for drilling as the SlipScreens one, and would be more expensive to replace if it all goes horribly wrong!

I used the Givi screen brace on the left side which they sell for use with their (non-Airflow) LC screens.
Feel free to PM me if you want to discuss further.
