this is a brand new Ford electronic locking differential i plan on using. its originally for 2011-2018 diesel 10.5" Sterling but will work on older 10.25" axles. part number BC3Z-4026-B

they are available brand new from Ford parts suppliers for an amazingly low price. i paid about 500$ for this, cheaper than any aftermarket limited slip or automatic locker, under half price of a air/electric aftermarket locker.

this with my front e-locker will make a great combination.
