Valve Cover Identification - Help!

[1968rt]

Digging through the garage and found a bunch of BB valve covers. I think the aqua covers are 68s and 69s. Have no idea what the black ones are. Any ideas?

I'm not the world's foremost authority, but judging by the original Mopars I've owned:
Top - '68 B-body, maybe other bodies - Bracket is for heater hoses & clip
2nd & 3rd down - '69 B-body, maybe other bodies - heater hose retainer moved to rt apron
Bottom - I think '70 B & E bodies, and maybe later
(All my A bodies were S6, 318 or 340, so can't help there)

Bottom black ones are 70 @topside nailed it on all of em.
