I recently bought a 2nd 2019 Ioniq PVEV because my wife wanted the safety features her 2013 Prius did not have. This 2nd car came with features I don't need including a cargo net. I would like to transfer the cargo net to the other Ioniq - the two knockout holes are already there and covered with blank plugs. The new one has the cargo net adapters in the two knockout holes. (See photos) I priced the two cargo net adapters at $24 each so I'd rather just switch the blanks and the cargo net adapters between the two cars. I have not been successful in finding out if they just pop out with a flat blade screwdriver, have to be twisted to a certain position before being removed or any other details. Has anyone had any experience with installing the fasteners for a cargo net? Thanks for any help you can provide.
