kickdown linkage

i have a 69 dart with a 440/727. i have a kickdown linkage that someone gave me, but its not the right one for the car. the car has an edlebrock carb and weiand intake. can anyone help me out here, i have a sale pending on the car, the buyer asked if i could put the linkage on, i said sure no problem, but being inexperienced in mopars, my uncle went to assist me in putting the part on, and found out its the wrong one. so i need the right linkage, can someone steer me in a direction where i can get one, or does someone on the board have one they can part with? thanks
