Ben,
I'm currently restoring a C-47 cockpit section & have found the following to be good sources;
http://www.retroaviation.comLocated in Shropshire, they've got a large barn full of mostly NOS C-47 parts, including the larger airframe assemblies. Very nice guys to deal with & very helpful.
http://www.skysportengineering.co.ukLocated in Bedfordshire, they've also got a barn full of C-47 parts. Mainly smaller asemblies, but well worth a check. Again, very nice people to do business with.
With both of the above, you'll be better off arranging to visit & sort through / collect your parts as they're busy people with their core businesses.
Further afield, you could give Nadine at American Aero a try (
http://www.american-aero.com). She has a great range of C-47 parts at good prices & is great to deal with. She was able to supply me with many parts that others, including Tradewinds & Basler couldn't source.
I have all the C-47 parts & maintenance manuals, if you drop me a PM with your e-mail address, I can send you scans of the pages you require.
Hope this helps!
Rich
