Throttle parts?

[screaminta]

I am in need of a new throttle link for my 250r, every parts store I see does not have number 7 on the fiche available which is the throttle link... I like the 250r throttle and want to keep it, anyone know where I can get one of these? Thanks..

I did some more searching today, and found that an '86 atc250r throttle link is still available. What is the difference between the atc and trx? I would think that they would be the same right? I know the cable lengths are different, but same carb=same throw? Please Help!!
