Bank Holiday weekend, so the couriers are all off until Tuesday so you are not going to get the part until Wednesday at the earliest and then you will have the ball ache of fitting the actuator.
In this instance, unfortunately I can only help you if you can supply the part number.
The part required will definitely be available from Nissan UK, Nissan Amsterdam, or Nissan Japan.
5th bow issues are a common issue.
Also for the avoidance of doubt, get your Nissan tech or parts person to identify the part required from the schematics below.
