This is a passenger side/right window regulator, removed from a 1986 Subaru Brat GL.  My parts book says this only fits Brat and 2 door hatchback GL/DL/STD models, from 1982-1987.  The hardtop coupe and wagons use different parts.  This car had low miles, and I rolled the window up and down a few times before pulling the door apart.  It worked as it should.  All teeth are in good shape, and everything that moves works smoothly.  Includes everything pictured, I don't have any more of the door parts sadly.
