Less rubber in the later designs, i understand what you're saying, just didn't want people to look at their balancers and see the numbers 00-00 and think they were safe. I'm sure that even though that part number is listed in Mercedes parts inventory, you can't order it. I looking at 3 balancers in front of me right now and can't tell the difference between 08-00 09-00 and 13-00, but 00-00 distinctly has more rubber(thicker band) than the other 3.
