It would have been nice for you to make a few posts and then start a new thread, rather than trying to hi-jack multiple existing ones.. but there you go.
Photos can be found online (try googling 'photos airliners' and take the top link..). Acurate dimensions or technical drawings are much more difficult to come by. I can't think of any available in the public domain off the top of my head. However, Kingston claims "excellent links with industry" so I presume you'd have contacts at places like maintenance facilities. Maybe speak to someone at Boeing? Although if you're anything like us it'd be Airbus...
