focus 4x4

Guys, im fitting a pair if rs side skirts to my focus rs project and was wondering if anyone could shed some light on how many fixings are needed - Fords werent a great deal of help over the phone as their diagram on their system wasnt that great. from what i can see is there are screw fixings at either end and clip fixings or similar half way down the skirt.Also are they bonded on aswell as the clips and fixings???
Any help would be very welcome - thanks
