Looking for a single diaphram brake booster. These are found on early to mid 90's Subaru's - they may be only on those with rear drum brakes but I'm not positive about that. Here is a pic, the single stage is the skinny booster on the left. If you have an old Subaru to part I'd be interested in picking one of these up. I may also be interested in the reservoir on top of the master cylinder..
