Well, you live and learn.

My local MB main agent wouldn't do the job as they didn't have the tool and so would only sell me a complete arm with the BJ in-situ.

I nearly broke my thumb knocking the old ones out with a 4lb lump hammer, I manufactured a drift out of a large impact socket that I shaved an angle off to make it sit square against the base of the BJ.

Where do you get the tool???????

Cheers,

Alex
