GM-51034-A Pins are used to align the cradle to the body during cradle installation. Both pins from GM-51034-A are inserted through the cradle pin-through-net holes and into the corresponding holes in the body. After the cradle is lifted into position, GM-51034-A pins are installed through the net holes in the cradle to ensure the cradle and body are aligned. Once the cradle bolts have been started, adjust the cradle using GM-51034-A pins. When the holes in the cradle and body are aligned and there is no binding on the GM-51034-A pins, tighten the cradle bolts and then remove the pins.
