My GUESS is that the odometer settings on these digital units are very tamper proof, hence the need to have one custom-ordered and sent from the factory.
Here's an idea...use a GPS or Mapquest or something like that and go for a 72 mile drive! That way, when you get the used unit, you'll be exactly matched up!
The legalities of all this probably vary from state to state. Technically, during your next registration or at the sale of the vehicle, you are probably supposed to indicate that the indicated mileage is not the actual mileage. That might kill your resale value.
Since the replacement unit has slightly MORE miles, I would not feel guilty about making the swap and forgetting about it. The best approach is actually to have the dealer do the swap so everything is on the up and up and well-documented.
Let me ask you this...how do you know it's the cluster and not the ECU?
