Stripped Power Steering Oil Line

Hey guys--

Just bought a 1982 280zx and working diligently to restore it!

I have a little issue that maybe somebody here has dealt with before.

I'm trying to replace the Power Steering Rack but one of the power steering fluid lines (metal with bolt-like head) has a bolt that is worn down to the point where a wrench cannot grab it successfully!

Any thoughts on how to remove it? Or should I scrap it for another line?

Thanks!!
