Gauge Cluster Swapping and Mileage Correction

I have a 1990 Celica GT that recently had an accident, causing the odometer, tachometer, and trip count to go fubar. I am in the process of getting a 1990 All-Trac cluster, but this cluster has over one hundred thousand more miles than my car does. How can I get the new cluster to accurately reflect my mileage without installing a new odometer from 0?

Maybe take the plastic cover off and turn it by hand??? I don't know if they have protection against this or not. I know the my car has protection against even a slim jim unlocking it so it might have protection against odometer fraud... Good luck
