i just put pins on my hood. i used the 69 1/2 a12 pins. the lanyards are only like 6 inches long, and connect right to the bezel. you'll never forget to put them on, as they are right there, when you shut the hood.
i used the bump stop location as it was already there, and the position was perfect for the hood. you might want a third in the center of the hood. i saw a car at raceway park in nj flying through the traps, with the center of the hood lifted up like a "V", from the air getting under it. the corners were pinned, but not the center.
