Throttle Pressure Linkage From Nothing

Lokar throttle cable. You'll likely need the kick down cable as well, assuming you're sticking with an Auto trans. They can come together as a kit. I don't remember what I paid but it was significantly less than trying to get the full linkage setup
My dart came with a half assed and dangerously frayed throttle cable and no kickdown. I used the Lokar setup and it took a little bit of fiddling but it all feels really good now
