The original part was functionally okay but the chrome has been worn off on one side.

I could buy a new one,but it'll be still be chrome plated mild steel.
Time for me to use my engineering skills and make a new one from stainless steel.
1 piece of 8mm diameter stainless, original is 7mm, close enough.
Turned the end to 6mm on me lathe and bought a Left hand thread 6mm die from ebay.

20 minutes later a left hand thread and a new nut again stainless and from ebay.

Chopped to the correct length, turned and threaded with right hand thread m6 die. Job done.

Finally with both ends threaded with corresponding nut secured and attached to the two ball joints.-
