Where can I get plastic pins for front bumper

I need the 3 pins (or screws) that go on the bumper to the core support underneath, and whatever 2 pins on top. I can't find anything. Dealer says it's discontinued. Next step is junkyard.

Latemodel Restoration carries a front bumper install kit that has those pins I believe.

I looked at that kit but nowhere does it say anything about the 3 pins that go underneath. I see 2 but not 3 so that won't really work for $20. I'm also wondering if there's a special clip that goes in that panel up top, unless it's the rivets? I'm confused.
