Here is a bunch of info in Acrobat form I downloaded for Dana Axles one day. There is a service manual and parts info and as used on data for most of the Dana Axles out there up till about 98. There is also a whole document on the Dana Axles used in Fords. Some body might wanna do a stickey or put it someplace easy to find. Some of the files are kinda large though. You should be able to find some info that will be useful if you're shopping axle parts.
