Headlight trim/bezel help

Hi. I'm new here and need help. I recently purchased a replacement passenger side headlight bezel and side marker for my 88 Caprice. I cant figure out how to remove the headlight and trim to replace it with the new. Can someone please help? I already have a star screwdriver to use. Thanks in advance.

You have to remove the headlamp assembly - there are three bolts on the rear of the header panel to remove. You should be able to reach these from under the hood, no problem. You will need a 10mm socket. If it's the passenger side, you will have to remove the battery. Once you have the lamp off, there are 4 Torx style screws that hold the bezel in place. I believe these are T15 but might be T20 size.
