Gear conection rod/shaft wanted ASAP!!

Hi im looking for the gear conection shaft that fits between the gear lever and the rose joint. I did buy one from ebay a week ago and it was too small, not good news I had no movement to change up gear and have a bike off the road in the only sunny part of this year so far due to a gear change rod. its so ironic such a small part can cause so much fustration, all I want is to get back on my bike after 3 months of healing and getting back upto fitness after my accident, time is ticking on too because I am in the forces and will soon be off out of this country again for god knows how long fighting other peoples wars for so called domocracy!! (JUST LET ME RIDE MY BIKE!!).

many thanks Ray.
