Depends!
 

First question:
Do you need a new Monovalve Body/Assembly? Or do you need a repair valve piston?

Second: the number you mention appear to be a production breakpoint that should correcspond to you VIN number sequence probably the last digits of the VIN, but you should do a search of VIN and Chassis codes and you will find the precise explaination of the coding and your answer.

If you need to repair the valve piston then you could check this out it may help.

Good Luck!

Unless your mono valve is actually cracked and leaking, the repair kit will almost certainly cure it with a minimum of fuss (4 screws). Try part number 000 835 0644.
