can anyone help me... I have acquired a zetec s spoiler (bumper and side skirts) at the moment i am trying to get the spoiler on first, its a 2001 ford fiesta mk5 (mk4 facelift?) I can see it has the 4 locking nuts (2 each side of the spoiler) where it would normally screw on...however because my fiesta not a zetec s model there no holes in the upper boot lid for a spoiler....my only concern to drill my own holes for it is on the inside it looks like its a double layer of metal so not sure how i will be able to screw in the locking nuts if i drilled in from the outside....any advise from anyone who done this before would be great before i start drilling holes otherwise i might have to go practise down the scrap yard on a car before my own car lol
