HELP! Rear lower wishbone toe adjuster - Cerbera.

[Boatbuoy]

Has anyone got the ability to re-tap the large adjuster thread (female) at the forward end of the lower rear wishbone? One of mine is not happy and is chewing up the threads of my new adjuster!

I'm currently on the Northants/Cambs border.

I'd be most grateful if anyone could help me out?

Regards,
Olly
