Reaching out for any advice on replacing my rear bumper cover. I've helped change a few on other cars and it was very easy. I have a 2014 LTZ Nox that has the 4 parking assist sensors in the cover. Can't seem to find any info on my cover as most for this year don't have the sensors. Removing the cover seems to be easy but I'm concerned about the 4 sensors. Also removing the 2 reflectors and facia on the top. Are these glued down? Also are the sensors glued in place from the factory? Can the sensors and reflectors be removed and used again?
