Hi there everybody,
I managed to get it all sorted, via UPS. The shipping cost was a bit steep, but for the piece of mind, the time involved I bit the bullet and got UPS to sort it all out.
Turns out the 7.40USD part costs 74USD to ship, it was only another two dollars to get two, so I have a spare or a backup. In case I screwed up.
The only difference I found was that, here in the UK, we have a 'dirty' version, as there is no air pump, etc as shown in Raymond's photos.
I was amazed how easy the car came apart, with a few exceptions, notably the bleed nipple and the gearbox breather.
If you're interested I keep somthing of a record of any work over on my msn space:

So thank you very much for all your help.
