Here are some pictorial references. This is how the 914-6 GT front hood catch-bracket was mounted on the famous #40 Sonauto Le Mans Winning 914-6 GT race car https://pbase.com/9146gt/image/22424656, and a photo of my OEM NOS bracket https://pbase.com/9146gt/image/22424655. The bracket is mounted using 3 bolts and a set of 'T-Barrel Nuts' that are welded in place at the front nose panel of the 914-6 GT. See here https://pbase.com/9146gt/image/23940054.
