I do not own a cobalt but I am looking into purchasing a 2008 lt sedan model because the four doors would be highly helpful for me. But my problem is I hate the tail lights on the cobalt sedans. Is there any way to exchange the sedan tail lights to the coupe tailights? I was looking at back bumpers and it appears that a coupe back bumper would fit on the sedan allowing me to put the round tail lights on the car. I know I would have to replace the trunk as well. But would this be possible? Or would I just be stuck with the oem style lights?
