Sorry I'm late to the party, but if you're still looking for technical data
http://aviationarchives.blogspot.com/ is an excellent source for LOT's of planes, including all 3 versions of Crusader. And he's always adding to it, and will look for data you request. The owner of the site is a former McDonnell-Douglas engineer. There are lots of lofting drawings for various aircraft, flight and maintenance manuals, and tons of other info. It took me days to search through the site.
For instance, I just started flying the Milton Shupe Invader, and he found a POH for me.
