If you think classic Mopar parts are expensive

My Wife's daily driver is a 91 BMW 325i convertible and I need to replace the brake master cylinder.
Not only did they come with 2 possible brake systems in some of the same years, but they are expensive little mothers.
250-300 just for the plunger section without the plastic tank.

Gees, I could replace the entire brake system on my Dart for that.:D
