throttle linkage rod

[likaroc13]

hey guys,

i had my tranny leaks fixed yesterday...on my way home with the truck, my gas pedal got stuck a bit...it has done that in the past...well when i parked it, i tried to rev the engine...however, my gas pedal wouldn't press down very far....so today i was trying to adjust the rod that goes from the throttle linkage down to the rod coming up from the trans (kickdown?)...anyway, the rod broke...so my question is what's the best route to go about replacing this rod...where should i look to get a replacement?

thanks for any help!

i'm attaching a couple pics for reference...it's the lower rod with the sleeve covering it
