The cover on one of the child seat anchors was laying on the rear shelf when I got it home from buying as a cpo so I thought I stuck it back on thinking it had just popped of. Well today two of them were off and lying there so I looked up the part number and it looks like the cover is to be attached to the rest of it from the parts diagram. C2C22456LEG Insanely Jag want $40 for this $2 piece of plastic. Should it be attached perm. or am I just looking at it wrong. Mine seem to have rough plastic on the rear and all 3 come off. This should be covered under the factory bumper to bumper right?
