I need instructions on swapping out a bumper cover. Just the plastic front please. For an 03 Sunfire

in not 100% sure its the same as the cavy but it should be.

theres 2 bolts in the wheel wells going from the bottom up. they fasten the bumper cover to the fenders, take those out. (i only put 1 back in for ease of removal.)
next there should be some plastic snap in fasteners in the middle of the top of the bumper. pull those out. (the cavy has 4, i only use 2).
finally if you have the front wheel well inserts then take the screws out that hold the bumper to them and the bumper will come off.

There is one bolt on each side going up into the fender near the wheel well, and 2 studs on each side of next to the headlights that you will need to remove the nut on. You will need to remove the front part of the fender wells first. You should be able to see all the bolts then. I have the older body style, so I don't know for sure, but there are probably screws around the grille area.
