Yes, that's dead easy to do Mick, the dials etc complete with their motors unplug from the PCB, allowing complete access to the PCB.

In many ways they are easier to disassemble than a 75 IPK, as the needles do not require to be removed from the faces.

Once the fascia is opened up, you will see the temperature and fuel gauges are separate from the rev counter and speedo.

The screws securing the mylar circuit to the back of the white plastic part, and then the PCB are removed, allowing the removal of the rev counter speedo, then once out of the plastic part, the PCB can be gently prised away from the speedo and rev counter stepper motors, which will leave eight "prongs" sticking up from the PCB, the interconnects between the motor and PCB are designed to separate in this way.

You can then exchange the 93C46 serial eeprom

Hope this helps, or if you don't fancy doing the job, as mentioned you can bung them in a box and post them up to me and I'll sort them for you
