BUICK GRAND NATIONAL T-TYPE REGAL 145 MPH OVERLAY DECAL
Why pay the high prices for a re-calibrated speedometer? Just install this overlay decal to your original speedometer and have the speedo shop recalibrate your existing speedometer.
Another option is just install the Canadian reducer to your existing speedometer cable located under the hood next to the power master brake system. This is a very high quality overlay decal and it will make your speedometer look 100% factory original. They should have built them this way from the factory for the Regal.
