Can somone here please tell me which model years had these wipers?

Thanks!

My parts manuals, dated December 1973 and December 1977, which are for right hand drive cars, only shows part #26370-E4100, with a pictorial representation showing the lower of the two arms in your photo.

This arm, from memory, is similar to that which I had on my Datsun P510 years ago.

However, I have just looked at three of my Zeds, all 1974 or older, and they all have the other arm shown in the upper part of your photo.

Sorry I cannot help beyond that. Anybody else?

Interesting. Thank you boyblunda!

I have 2 '71s, and neither of them have either of the wipers shown. Darned POs. I like the wire type.

I'll add that my 78 280Z has the upper one and my 79 810 has the lower one. They're both cars purchased from the original owner with low mileage and I have no reason to believe they're not original.
