Thank you. I'll return the piece to the body shop--it's probably off someone's Corvette.
Yes, I will find some round-head sheet metal screws the of the same thread size as the hex-head ones in the picture. That will definitely work.
A forum member recognized the sockets from his '68 GTO. He sent me a pair with pigtails so I can splice them into the front harness. I believe Tempest's/GTO's used these from '68 thru '70. I don't know about the '69 Firebird.
