Just thought I would make this post as an FYI to anyone who needs their compression arm bush replaced.
You can get a genuine one for around (Exchange rate dependant) £22 delivered from an Infinity garage in the states. I ordered mine on the 13th and it arrived yesterday so 7 day turn around.

eBay store if link goes dead: http://www.ebay.co.uk/usr/ocinfiniti
$19.95 + $15 USPS delivered, tracked to your door.
I know there have been posts about a none genuine one appearing for £30 on eBay so this is a much better bet. Since the value of the item is so low there is no import duty to pay.
Hope this helps someone out
EDIT - Looks like they have added a quicker shipping method to the listing which is quite expensive. Ask the guy for a USPS First Class quote as that what I got for $15.
