Lower fork tube assembly

Not to upset the apple cart here, but a lot of Z1 owners turned their forks around.  

My other concern is the OP said he had 1974 Z1A lowers, but mentioned it has lower caps with arrows. 

Same principle applies. Gap to the back. If you look closely you'll see the casting line on the forward section of the clamp. Hard to miss.

I think the caps are interchangeable from 73 to at least 80, if not later.

Funny how people envision the same situation. I went to the wrong forks, HRM goes to wrong axle clamps. That never crossed my mind. 

NO! caps are not the same for Z1 to the KZ they are 2 different thickness's or something like that. I have sold a few, both styles over the last 20 yrs.
