13 door changed starting 2007 following a factory fire in 2006. It is now taller. I believe they still sell both. The old pre-2006 door might fit, or at least come close. I vaguely recall the width is different, but how much or in which direction I can't recall. Perhaps someone will chime in.
On the other hand, you might attempt a repair. The doors have a wood core that lends rigidity to the curve, but water infiltration can rot that wood and allow the curve to relax. Some have cut out the wood core and found it completely saturated!
Some people make a new wood core by cutting kerfs in a piece of plywood or ODB, gluing it on and fiberglassing it in. A jig is normally used to make sure it fits the correct curve. One person created a steel frame shaped to the curve of the shell filled in with some foam insulation and fiberglassed over that.
The horizontal crack can be repaired as part of the process.
