I did exactly that a couple of winter's ago when I hit a patch of ice then boinked against a tree skidding backwards. What I did was a I found a very good tailgate at a junkyard that had jeep parts for $50.00. Then I took it to my favorite body and paint shop an they painted it to match and replaced it onto my Jeep for $380.00. It turned out real nice. Later I had the same body shop paint a pair of new replacement fenders that I bought from Daveys Jeeps and
they painted the pair for about $400.00. Maybe that gives you an idea.
