Oldsmobile/Buick: Master Brake Cylinder, master brake cylinder, steve cunningham

Question
I am looking for a new, rebuilt, Master Brake Cylinder for a 1987 Oldsmobile Touring Sedan. The Touring Sedan is in the " 98 model family".
The reason I cannot say i'ts just a 98 is because the Touring Sedan is unique among the 98 models.
In 1987 the Olds "98 model" had three vehicles,  "Regency", "Brougham", and "Touring Sedan". The Touring Sedan was the top of the line, and it also had a completely different Master Cylinder from the others. The VIN # 1G3CX5130H4344026. Any help would truly be appreciated. Thank You Steve Cunningham

Answer
Steve,

I know it sounds awful but did you try a junkyard ? Usually when I go they can also give you another vehicle that has the same size master cylinder that would fit . For your car I don't know exactly where to find one or what would fit .
