Dana 60 vs Ford 9"

DBrown, if you buy everything new it just plain costs more to build a 9 inch than a Dana, look it up. As for factory N cases and whatever, glad you found some, you can't find anything like that around here. Also those are the ONLY good factory cases and like I said they are scarce in many parts of the country. Even still the aftermarket stuff is better than they are by a bunch. If you are using crappy factory stuff you might just as well use an 8 3/4, it's probably stronger.
