I ended up contacting Struts Australia and i've got to say their Sydney office was fantastic. I ordered my replacment part (metal ball stud cup) online from their Melbourne Head Office and got the wrong part (the code was different to the part number). Called up the Sydney office as that is where i'm based and got my replacment part PLUS a spare just in case for no extra charge.
The bits are soo much stronger and better built than the originals ones, so i ended up using the spare to replace my original un-broken part as well. Much better fit and much stronger. So if anyone else has any troubles with any parts of their strut or damper give them a call, they'll be able to help you out.
