those two are rivets, they have to be drilled out. then you have to by new ones.
you also have 2 screws on each side on the front of each wheel weel
and along the bottom where you have the little lip, on the bottom of the rad support, theres like 4 or so clip. there's a better way to describe them but i'm too tired right now.
funny thing is i took my front bumpper off today, bad thing was the 2 nuts on the inside fender were so rusty that they broke off at the bolts.
