Ok so I searched and found the threads pointing to order sachs/kyb shocks/spring assy for like 81 bux but it says it is for the ML430, will this work on my 99 ML320?

Also want the latest "re-valved" version, does anyone know the part numbers? I know the MB part is 163-320-23-13 but what is 163-320-24-13? Left or right side? I do not have the spare tire carrier on the back. Help! haha.
