Hey Macca i assume you have a GU with an Airbag? Obviously otherwise you'd be whipping off the steering wheel and fixing it that way. Have you called Nissan and asked them if they can remove and refit your steering wheel? Surely they'd be able to isolate your air bag circuit to get that done? If there is nothing wrong with your drag link and you dont need the upgrade then maybe look at that.
I am a big fan of the upgrade though fella, its the first thing to arrive at that rock! if you are going to bend something int eh front of your Nissan it will be your drag link so a stronger one is a winner.
