Window Glass?

Received my window glass for my 26T Sedan. The windshield, two door panels, and the rear glass were correct. However, they sent me two cust pieces of glass for my rear windows that are not even close to the correct size. The company jobbed it out and has no idea what these two pieces of glass were cut for! Any of you have any ideas? Here is a pic (I hope it posts)

There Wind-wings an assessory at the time. They mount to the windshield posts with clamps on a roadster and brkts on a coupe or sedan to the door frame. They go up and down!! They look a little big though. should be about 3" wide.
