Identify these hub caps, never seen these

[Vette40th]

I am at my Dads, and he was showing me all the old parts he had laying around, and I saw these hub caps. Never seen them with the emblem or the one with disc brakes on it.
And these valve covers from a a 283.
Any idea if the disc brakes are Corvette, Camaro or just a hub cap used to identify any GM vehicle that had disc brakes.

Yes, those appear to be the 67 only center caps for the 7” wide rallye wheels. They have a much shorter “derby” than the 1968 up center covers.

Thnx. I have never seen or really paid attention to the black emblem in one, f, and the disc brakes on the other.
The black emblem center part is just the tall hub caps, vice the 67 short ones.
