So when you say "Improved balancers entered production as of engine end number 661775 for V6 and 166563 for V8."

You are refering to the last 6 numbers of the "11394460007935" number that is listed on my NETSTAT VMI printout for my 1999 AMG C43 manufactured on 5/7/1999?

That would mean that I have the bad part even though the car wasn't produced until May?
Thanks
