hi im fitting my cosworth kit tomorow to my 3 door, ive seen on ebay for sale some cosworth spoiler brackets, but will i need them? or will just some sikaflex do to hold it on as i dont like the thought of drilling holes into good metal, or should i put some bolts and some sikaflex in just for safety? any one got any piks of these brackets and how they are used or if they are to any importance?

 

Sikaflex and a couple of self tappers/ bolts
