Its hard to tell with this pic, but if you look at the bottom corners you can see the little indent below the hood insert bolts there is an oval shaped hole:
Left side: Below corner insert bolt to the left, you can see a speck of white(wax), that is where the hole is.
Hope this kinda helps... I don't have a picture of the stock hood... Here are a few more pictures with different angles.
UPDATE: or did you mean the bottom side of the hood where the tubes are "tucked" in?![]()
