Accelerator / Gas Pedals identification

[zed2]

I have two (2) styles of Accelerator / Gas Pedals

Does any know the model/production year of these?

Thanks,

Keith

Others will have more detail on dates for when these started and stopped etc. 

The one with the with the extra tab on top (left on last pic)is for the early 69-70 cars. That tab is where the hand throttle cable hooks up. 

The one on the right is the replacement for that, after the hand throttle was recalled and omitted.

Looking at the online catalog: http://www.carpartsmanual.com/datsun/Z-1969-1978/engine-240z-260z/accelerator-choke-throttle

The one on the right is possibly from a automatic transmission car due to the metal tab on the rod below the pivot ball. That tab is shown in the catalog image.

The one on the left is the early model for the throttle cable as @Terrapin Zmentioned. The online catalog shows an end date 7001 for item #20, the throttle cable.
