Hello everyone, I saw this back panel of an air cleaner box on ebay and noticed it had a choke cable holder arm that is not on my Z. I was wondering if all Zs had them or if it was year specific? I did a quick check and my '72 didn't seem to have a mounting bracket for it. Any help is appreciated, thanks!

Bump this up. I'd like to know too.

Here's mine, '72.
