Kerry, Thanks for the quick response and information/advice. I went by a Mercedes parts distributor in my area, (Washington, DC) Brinson's. They have always been very helpful in getting me the right parts for this car. They pulled up an exploded diagram for my car (see attached). According to what they saw my car is supposed to use the harmonic balancer/dampener #101 pictured in the exploded diagram. The problem is that the hb/dampener I pulled off is identical to the hb #26 in the diagram. This is NOT the first time that the parts I have on the car dont match up with the "book" and I never know if it is an error in the book or some artful parts swapping/adaptation by the previous owner(s). For example there appears to be a 240D heater control in the console. It is my fervent hope NOT to keep putting the wrong/adapted parts on the motor
