Another source is Ford Motor Company.com They can link you with archives and you can muddle your way from there. The site is a wealth of information but it is sometimes rather difficult to navigate. If you are new you might enjoy some of the discoveries that you make along the way, I did.

For free, a web search is your best bet.  there is some good information.  The Knovel book is the best http://www.knovel.com/knovel2/Toc.jsp?BookID=822 but you will need to go to a library that suscribes for access or use interlibrary loan.\n\nThe yarn CD on this site might have the info.\nhttp://www.ncsu-engineering-resources.com/store/trans/productDetailForm.asp?imgid=80&seq=0&CatID=15
