Thermoquad throttle and kickdown linkage

Converting my 1969 dart 318 2bbl to a thermoquad and 340 manifold. I have the 340 throttle bracket installed. Which side of the throttle arm on the carb does the kickdown and throttle linkage go? And how should I go about lengthening the throttle linkage by 1/4"? There is plenty of cable but when it is clamped down it is held slightly too far back. A pic of a similar setup would help immensely
