350z rear suspension problems

[knowlsey]

Hi there guys

 

Can anyone tell me what and where I can get this part from ?

I have a friend installing all my suspension for me ,but Im overseas at the moment so trying to organise things from 4000 miles away.

He was installing rear coilovers and toe and traction arms and it managed to snap he said it was mounted on the rear subframe.

 

Thanks

Matt
