Michael B San Jose , CA March 30, 2020 Upper spray arm, ordered part and also screw and bearing because others had done so it was the correct thing to order. The repair was easy however the ordering was excellent and delivery next day Took out the tray at the bottom. Checked the screw and bearing would fit.
