I have a big brake 60 which had front end damage before I recieved it. I am puttng a new jig front clip on it. Question is, not sure how the big brake ducts mount. I looked in the "aim manual" and it shows a small picture with screws. Does anyone have a picture of how the hole should be cut in front of the duct, the part you can see looking through the grille? What type of screws are used? size? Philips or ?? Any help with description or pictures will be appreciated.
