I have been provided with alot of info on Ford 9". Thanks. I am now looking for a 9" from a 66-77 Ford Bronco 58" wide or 77-81 Granada/Versailles 58 1/2" wide. Next I plan to get a conversion kit to use Ford Explorer disc brakes. Then for a good highway gear maybe a 2.75 ratio.

1) What Fords commonly have a posi/limited slip rear end?
2) What rear end ratio is commonly used in a Ford Explorer?
