From the below site I figured out how to replace the Toyota Sienna trunk handle
http://car-repair.wikia.com/wiki/Sienna_broken_back_hatch_handle#How_to_fix_a_broken_back_hatch_handle_on_an_early_model_Toyota_Sienna
However , What is the exact part to replace this handle with. I didn't find any part called just handle. Is it Tailgate handle that they are referring to which is shown in this link http://www.beanworthy.com/19982003-Toyota-Sienna-Plastic-Liftgate-Tailgate/A/B003PVD7SS.htm
