I bought my 'speed nuts' for my hood scoops from Pepboys ( in the 'help section'),I suppose Autozone, NAPA etc all have them..... I also siliconed the joint between scoops and hood, because I had installed under hood insulation , and my scoops would leak, you dont want to trap moisture in there it will rust, if no hood insulation,no problem but if you have insulation ,I`d seal them...check leakage before installing insulation..
