A tab may have been added to the bottom of your early pedal, or a linkage is used to convert "pull" to "push". The pictures don't show this clearly.
The hose running from the secondary master cylinder port should be anchored or supported at the junction to the line, not left floating. I can't see the primary line, but the same would hold true for it.
Actual push rod clearance to the primary master cylinder piston can be very small (.020"-.030") as long as your pedal
fully returns with
it's own return spring. This will minimize actual pedal "free" movement.
It's very important to be sure the pedal can fully stroke the master cylinder
before the pedal bottoms out.
