Can you not remove the odometer from your old cluster and put it into the new one?
After I junked my old Celica,I kept the cluster out of it and tried rolling it back. There is a little pin/lock deely that keeps the odometer from being moved freely unless the wheels are rolling. I had to hold the pin in it's unlocked position and used a drill to spin the odometer. However, 637 revolutions was equal to 1KM,so you'd be sitting there for a loooooong time to roll it back. When my grandpa and I restored our old Mini Cooper,we sent the gauge cluster away to be refurbished and the guy rolled the odometer back to 0 but I don't know how he did it.
I'd just try swapping the odometers if possible,which I don't see why it wouldn't be.
