I came across these items while cleaning out my parents’ basement after my father passed. I don’t know much about them other than the fact that my father used to restore Corvette's while I was younger. There are 7-Gas Caps, 3-Horn Buttons and a shifter nob.
From my research, these are the years from which these parts are from:
1- 1965 cap
1- 1966 '' ''
1- 1967 " " (red)
1- 1975-76 " " White unleaded
1- 1971-77 " " Bare Metal
2- 1984-90 " " Black & Silver/Gray
