B2 axle tag

[fastbigblockford]

looking for a D28 to replace the ghosted unit in my '87, a friend found a B2 today and snagged the tag, unfortunately he snapped it off instead of unbolting it, but here is what i have
6O7C
4SL10A756CO6
is this a limited slip 7.5 w/4.10 gears?? im not sure but i think it is. tag is from an '85-86 B2 2.9 auto.
thanks in advance for any help.
later
Daniel

yes it is! that must have the illusive plow package or something

Edit:
that's the rear diff tag... but the front would have 4.10's too
