Changing Speedo..... how to set odometer to match old one ?

[DonnieLawson]

Im replacing my old 120 MPH speedo with a 150 mph in my 68 Cuda.
I would like to have the same mileage on the new one if possible .
Is there a link or someone with knowledge on how to do this ?
My car is getting closer to being ready to reinstall the dash
Thanks guys
Donnie

I love that rotary pay phone you've got on the wall !
"For a good time , call : TOpaz-75309"

As far as the odometre is concerned ... can you swap the odo from your 120 original to the 150 replacement ?

The 150 has a trip odometer on it .
I can look and see, if it would work , that would be the ticket


Oh yes......... The phone works !

If you take both speedos apart, you should be able to swap the odometer numbers. Just make sure your hands are spotless.
