In my left hand I use needle-nose vice grips to line it up and steady it - and then with my right hand push it home with the flat side of a screw driver. Release the needle nose pliers. Done. I find that where you eye-ball the actuator rod helps too - Instead of looking up at it from below, I look from the BACK side of the sub frame, looking above the sub frame, facing the front of the car, which is the same direction I am pushing on the clip.
