I think your best bet would be used parts. Do a google or yahoo search for used auto parts. There are sights that list thousands of parts in many states. The other possibility is an auto/body shop. They have manuals that show them every little part and how they can order it for a re-build. Might be pretty pricey however going that route.
The door in my van is hinged at the bottom and tilts out about 45 degrees. It has CD slots in it. We just use it for utility.
Best of luck
