Help me identify this paint color

[SavageC20]

I am planning on painting my truck soon and I am trying to identify this color that was on my 72 c20 when it was repainted in 1977or8. I really like the way it looks and want to bring it back. A family member of the original owner said he thought it was a color from a 1967 or 8 corvette. I did't see anything that looks exactly like it online. I also checked 1977-8 corvette paint colors and the closest I found was international blue, but it still looks different to me. Any help would be appreciated.
