Roof rack removal help

I would like to take my roof rack off to re-do some silicone in the bolt holes. However I've heard of a few instances where the yellow plastic screw tab that is at the front of the roof rack break when trying to remove the rack. Was just wondering if anyone has had success with a certain technique that kept the yellow tab intact

Slow and easy straight up. Not in the winter. I would put it in the sun for a few hours.
Keep a couple on hand just in case.

 

Thank you so much for the part number. I'm going to the dealership Monday to order the part to keep on hand just in case.
