I would go to the junkyard and compare a sedan and coupe trunk lid, and see if the curvature is similar.
Or you may just have to be the pioneer and give it a try. If it doesn’t fit then you can sell it and make most of your money back.
Since I'm 16, I'm not allowed into Junkyards or Pick a Parts If this doesn't get a response soon I'll probably just go for it. I have some Christmas money. Thank you all for the responses
