Lude Generation

Hi all,
MOT on Friday, and I've just sheared the thread off the ball joint on the rear upper arm..
The bloody thing is rusted in tight so I cant get it out - gonna have to find a replacement...
So...
Does anyone have a passenger side rear upper control arm with the ball joint for a 4th gen in reasonable nick?
I'm told that a 5th gen would fit too..
Appreciate any help on this chaps!
Cheers
Doug

few 4gen here with good joints and new dust covers

Thanks mate - I have one on the way to me now..
Thanks for replying though!
