Thanks Eric, I believe the 722.3 has a different valve body. I found this website

Which would have been perfect if I had a 722.3 or 722.4. I did look at the plate and could only find the marks where there are already balls. I am not sure which "level" they came from. Did mercedes make a 722.118 manual? Is this a needle in a haystack? Thanks, I really appreciate everyones help.
