So I ordered the Lucid Bear center caps thinking I would replace the "Lucid" labeled center caps in the Plastic 19" Aero Range wheel covers. But that doesn't seem to be the case. I have tried many things to remove the center cap including a 2" levered suction cup, but nothing works. The backside has a mechanism that looks like it would release the center cap, but I haven't been able to. Has anybody done this?
