Paul, The accumulator in located in the frame, towards the back of the car. You will see it nestled up there in the frame.You can also see it on my web site. The Bosch number is 0-438-170-029. Check out my price and don't let them get to you to bad. You need stubby wrenches and patience to get it out. John Hervey Dallas, Texas http://www.specialtauto.com/
