Need help!

i'm 97% done with my 71 stang, found two unmarked parts in my box.Can some one help identify them? Pic attached.

Today I found out where this part goes.Inside,below the rear quarter window to hold the inner panel.

looks like the piece to hold the radiator onto the core support. I havent poked around on my 73 in a loooong time though.
