That's inaccurate, sorry.
The hinges are separate from the pop-up hood actuators. The actuators are terribly expensive from Nissan UK, however I could help and source these cheaper. I fixed my Nismo with similar damage and I went through all of that. You will also need the little ECU that deals with the pop-up hood system, as the crash is recorded on. I might have a spare somewhere, will need to check.
As Alex said, you can also buy the delete kit, not just the hinges, but the pop-up hood disabling system. This will however invalidate any future insurance, if the system is meant to be live / working.
You will also need the UK hinges if you want to keep the pop-up hood system.
Perhaps let it be written off and buy another one would be a better idea.
