Step 29
Take the spoiler and turn it to the back and drill two
holes of 7 mm with a distance of 50 mm in total. On the back of the
spoiler there are 5 mm marks to make drilling easy with out the use of
measuring tools.
Place the spoiler on the wings stay and put the black
plastic washers on top. Then use 3x12 mm round head screws to secure the
spoiler to the wing stay. I had to use screws from the emergency screw
package that comes with the kit!
Nice that there is a metric marking
molded on the back of the spoiler!
