I got a bentley grill off ebay for my 05 sebring. I am assuming that I will need to take the whole front bumper off to replace the grill. I see the 4 black clips on the top and the 8 or so black clips underneath. Do i just need to remove all of these clips and remove the screws in the wheel wells to remove the front bumper? I was able to get the top 4 out but coulnt get bottom one out for some reason. Is there a trick to remove these clips?

Are there any other tips to do this?

Thanks,
Frank
