BB Valve Cover ID??

[travlnz28]

Picked up this nice set of covers and I can't figure them out. I looked through Cranes covers and couldn't find them. I am thinking late 1971 up Corvette. Any ideas? Are they mismatched? No indent for PS. They have a small notch at the back of the driver side. They have been hanging in a guys shed for many years.

They have drippers.

I am not sure when the changeover was, but I believe the late 71 up would have a push in oil fill cap like the 72's
The right side one has all the clips for a 1970 L34, L78 & LS6 and would have been chrome. The left side looks like 1969.

Yes, the right side is the same as my LS5 except for the chrome. The thing that confused me on the left cover is the outward notch at the rear.

maybe they are 69 some one dechromed and painted as far as i know only 69 have that bump in the rear of drivers side
