The only US market Subarus with 4.44 LSD final drive are the '04+ Forester XT manual, the '04+ Baja Turbo manual, and the '00-01 Impreza 2.5RS automatics. The '98 and '99 Impreza RS was also 4.44 in the automatic, but came with a standard open rear diff.

If you need the gears themselves (physically) and not just the information, drop me a PM.
