I found rust-free doors for my Oldsmobile at last, at $100 per door plus $300 for shipping, and I thought I would share with everyone my source: The Arizona Automobile Recycler's Association (AARA).

You can search for parts, or simply request them. Within about 5 minutes of submitting a request online, Tom in Maricopa contacted me back by phone with the quotes. If you guys need parts that are rust-free, the AARA is definitely the place to look. My father used them several times in the past 15 years, and they've never let him down once.
