i have a 90 240 and i hade to replace the master ,,it cost me only 20 bucks from auto zone..my advice to replace the slave master cylinder as well..known to some as the clutch pump..when u replace the master only the pressure will build up and blow the slave sooner or later,,i bought both for a total of 45 $ ..autozone ..good luck
