Correct 70 440 oil cap?

Have a few oil caps collected over the years. The caps on the right have 4 dots (hard to see) that are later 60s, one raised center and one with lowered center. I think the ribbed centers are 70s. Not sure what should be used on my 1970 440?

Do they have any markings on the ears? I know that 71 will have an F on one ear and an E on the other. Thinking 70 is either the FE cap or maybe one that has an S on one ear. Not sure.

The 3 on the left look like 74 and up caps. 71-3 used FE caps.

Far right, F/E

Also pretty sure that 70 was the first year for the twist on cap. Push on 69 and back isn't it?

Thank you Mark and Stew for your input.

Need to check but pretty sure they have the F/E on the ears. The one you show Mark is what I believe is correct.

70 is also F/E

The cap does have the F/E. That will be the weener!
