You bought a new diff or you just want to know ? I recently bought the alloy differential and its the same diff as the adjustable one. Exept for the shell. If you have the standard alloy diff shell you cant adjust it, only poke things into the hole in the diff housing
Otherwise there is supposed to go some kinda screw through that hole that you adjust from the shell.

Guys, do these adjustable diffs use the same soft diff covers that come stock on the FG cars? If so, I'm disappointed. My diff covers is really getting grooved, and I'd hate to spend the money like you guys did, then get big grooves again.
