ok, so i was searching a site for used rear axles and it brought up some questions.

first question: on the site, there were 2 choices -

8.8" ring gear, 10" brakes, 4.10 ratio, FX4 (locking), w/o Level II
and
8.8" ring gear, 10" brakes, 4.10 ratio, FX4 (locking), w/Level II

and i was wondering what the difference is between level II and not level II

second question: the same axle comes up under these two selections

8.8" ring gear, 10" brakes, 4.10 ratio, FX4 (locking), w/o Level II
and
8.8" ring gear, 10" brakes, 4.10 ratio, exc. FX4

in the description it says 4.10N V330L and its off an '04 ranger. is there really a difference? or would i need to just talk to the company about it?

either way i don't have the money to get it, i'm just trying to figure some things out. thanks for the help.
