Hood Ledge
The exterior fenders bolt to the inner Hood Ledge pieces, which are welded to the chassis rails at the bottom. The rear if the ledges are welded to the Cowl and at the front to the radiator Core Support, completing the box-like structure of the front sheet metal (the Engine Bay). And as you might guess, the bonnet (hood) lies just above the top edges of the Hood Ledge.
