I believe so, BUT your gonna have to have Sunfire tails.
i've swapped the cavy trunk lid onto my 4 door sunfire and only ran into a few problems, and yes, you'll need sunfire taillights. I still have the sunfire tails on my car with the cavy inners and it looks ray-tarded.
but easy install, couple a bolts and a couple of cuts and splices.
mind you that all cavalier trunks are the same, while only the sunfire sedan will bolt up, the coupe is totally different.
Ill make a sig someday
I have a sedan that Im looking to swap rear ends. PM me
