Are all 46-47-48 Chevy rear fenders the same?

I'm looking for a right rear fender for my 48 fleetline aero sedan and I was wondering if all the fenders for those years were the same......will the fenders off a coupe or sedan fit??

thanks

 

All the Chevrolet passenger car body styles, including the Sedan Delivery, use the same rear fenders in 46-7-8, possibly even 42 have to look it up.
That said there are differences, not in fit but in holes for gas filler and trim.
