Ok I could use some helpful advise from the members here who have performed the auto to manual swap on a CD chassis.

I have read and searched but couldn't find an anything.

My concern is regarding the use of the 12mm nuts as spacers on the cabin side when mounting the clutch master cylinder and bracket.
As you can see in the first picture when I use the spacers the plunger does not reach the corresponding hole on the pedal.

The second is with the spacers removed, and everything lines up correctly.
Am I missing something here?
Do I need these spacers, have you guys used them in your swaps?
