detent cable adjustment

[71chevylowrider]

I recently had to do this so it's still fresh inmy mind, I couldn't figure out where the adjustment was, it's kind of hidden on the cable right behind it's mount, have someone sit in the drivers seat, lift up on the tab that unlocks the cable, have the person in the truck slowly push the throttle to the floor, & then pudh the tab back down into it's locked position.
