Hey, that's a Sled City Scoop that comes with a no blow off? no cracking warranty for only $300. Everyone knows that the scoop goes in the center of the hood. Right? And everyone knows that the scoop goes within an 1/8th inch from the back of the hood. Right ? That center opening stud is in the center of the scoop and naturally goes in the center of the hood. Right? Drill the center opening stud hole first. Have some tape on the hood where all the studs will be hitting the tape after you lay the scoop back on the hood. Do your measuring to center the back of the hood. Mark on the tape where the studs hit the tape. Drill your holes. If you are mounting the scoop to a steel hood, you may have to use a hole saw to cut the bracing for your fender washers to lay flat. Side and rear studs are 10-24 and center opening stud is 1/4-20
. Use the type of locking nuts with the plastic inserts. On the center opening stud use a 1/4" stainless steel small flat washer on both ends of the chrome plated plumbing pipe that you would use under the bathroom sink. Cut to proper length. Sometimes the side bolts get bent in shipping, Thanks FedEx, and just take a plyers or a small cresent wrench and gently straighten.
