My local Subaru dealer allowed me to test fit a set of AVS vent shades for a 2000-2004 Legacy sedan on my 1997 Legacy sedan. The fitment is great. The part # for these is 94832. These retail for nearly $100 less than a set of used jdm rainguards. I thought I would share this info with all of you.

part # I posted is for a sedan set
