I have a 1974 charger and i am removing my throttle cable. I was wondering how you remove the actual throttle cable from the firewall? It has a strange set up I haven't ever messed with.

From the inside there are 2 tabs that you squeeze and then it pushes out. There may be a metal retaining strip that you pull out first.
