You see, i need only the left side tube, not the whole kit, and if i buy only two parts at worldoftriumph.com , it will be 150 pounds with delivering (the whole kit You mentioned costs about 180 pounds).
That's why i have a hope, someone have this parts or only the left rail(because it's delivering is very expensive for me)

And what do you mean "I can make you a left side frame"?
You can do it yourself?Or You have one?
