Jason, pull the bow back and have someone mark the cable rod at the back of the slide. Now you can set the cord length by just pulling the slide back. Set it so the rest is fully up at this point. If the cord is too short it'll drop too late, and bind the cables. Also, look at how the cord is attached to the rest in the pic. This makes a big difference. I have a Shakey hunter on my Liberty, and an original on my P40 Dually.
