Throttle Linkage

Is the linkage adapter necessary if your using lokar throttle and kickdown cables?
No, you do not need the adapter if going lokar.
I just installed the Lokar setup on my 5.9 and the instructions show connecting all their stuff to the carb without the use of an adapter. Heres a couple of pics of my finished setup. After adjustments I had the wife mash down the gas pedal while I looked down the carb and it was wide open.
