Help w part number windshield cowl

Somehow I lost the drivers side cowl/weatherstrip piece where the windshield meets the A pillar and hood.
I’ve attached a pic of the left (passenger) side that is still in place. Need the drivers side piece and I’ve searched the Toyota parts portal online w no luck.
Anyone have any idea on what to search or how to find this part no?
Thanks

here's the procedure:
