Looks like you just need the header panel. Not sure if the radiator support was damaged or not but if it was then you'll need that too and maybe a radiator if it's messed up. Headlights look good which is a plus because it's easier to find a header panel without headlights sometimes. People take the headlights out and sell them because new they're somewhere around $100. Any header panel from 87-90 will do just fine.
That's what I'm talking about but I recommend checking your local junkyards. You should be able to find a 87-90 Caprice no problem usually and you can get the whole peice you need. It's real easy to remove and install. Can't remember exactly but maybe 5 bolts each side for top corner of fender and a few bolts each side to the radiator support. Just unplug all the lights from up there and it's not even that heavy either.
