Titanium Steering Knuckle

HI i've got Basher 1/16 4WD Mini Monster Truck V2 - HellSeeker. You wrote :" But it's an off-road monster truck so, eventually, you're going to break something so there is an extensive range of spares and upgrade parts in stock and all the parts on the V2 are cross-compatible with the original Nitro Circus Mini Monster Truck".
I need the Titanium Steering Knuckle to this car which you've got in stock but I couldn't purchase it.
I chat with one of your advisor and she told me that you don't have curier ehich would deliver this part to Ireland. Can't you just send it in regular letter by post office?
unfortunetely you are the only supplyer , and I need that part.
Please e-mail me the solution- how can I get this part get this part so your sentence about spare part from advert become true?!

thank you
looking forward for your answer
