air gap linkage issues

I just changed the accelerator cable on my Dart two nights ago. I used this one from Lokar.

My car had the 45 year old original six cylinder cable on it. Took me less than 30 minutes to install. I went ahead and replaced the return springs and added the kick down cable as well. Best money I've spent on the car in a while.
