4 door to 2 door

Good looking project waggin. What is the donor door from?

What I was thinking was to get donor doors from a 2 door Dart. Mount them on the hinges and then move the post back to the proper location for the new door. Then use the back door from the 4 door car to make a solid panel that would become part of the quarter panel. That way I would kind of get the best of both worlds by have a larger door for me to get in and out of and also get the ridgidness of a post car for any extra HP I might want to throw under the hood.
