changing speedometer
 

My 81 has an 85mph speedometer. Does anyone know if the speedometers from later 1st gen RX7s can be swapped into this car? Has anyone put an aftermarket speedometer into their car?

I have a 1980 that came with the 85 MPH speedo and have replaced it several times with speedos from a '79 and from later 80's models.

Once you remove the cluster there's only 2 screws holding the speedo in place.

It's a pretty simple job.
