I have two (2) different style/size sunvisors in my spare parts collection:

The upper style matches the one in my 1970 240Z.

Can anyone identify the year and model of the lower style?

Thanks,

Keith

Fiche suggests there was a change on July 1972

Somewhere later than that they grew pockets too. Mirrors too??? Naw.

Oh great now I have to check all of mine. I thought the pockets were the change, but shape / length is another one. 

Interesting red and white are 1 month off the rest.
