Sierra Denali AWD V8-6.2L (2008)
Start by installing the center piece of foam vertically at the hole (1) in the fender 20 mm (3/4 in) above the right fender retaining slot.
When attaching the foam, try to keep the foam uniform and even across the top for appearance purposes.
Attach the other two pieces of foam vertically with no gaps to the left side and right side of the center piece of foam as shown above.
