You can also buy the individual sockets at Sears.  I prefer a 1/2" drive for
the diff plug, as they are sometimes extremely tight; and a 1/4" drive for
the brake adjuster.

I've also been known to replace the plugs with hardened hex socket plugs
(from MMC), which seem less apt to strip and at least in some circumstances
easier to access

MMC also has them in magnetic, which I like to use for drain plugs
