I am going to try the old 10mm wrench taped to the end of the batten...again...but last time it took me forever just to get one in the middle of the track, so I don't know how long it will take to do 20 of them!
Double sided tape, the right angle on the bolts/beam and practice..
Be happy that F16s are only 2.5 meters wide and have a beer.
