Cluster and Odometer question...

When I swap out my cluster from the PGM-FI car, do I have to take the clusters apart from both cars and swap out the speedo so I can transfer my miles over, or can the odometer in the donor car's cluster be changed? I heard they have tamper-proof dials or something, is this BS?

I just want to keep the miles correct with the car.

thegreatdane used a drill to correct the miles....

u can just swap the whole piece over

yeah you can just unscrew the old speedo gauge and move it over.
