[W126 Coupe] speedo correction?

[Divov]

I was hoping I could take the cable drive gear out of a 350 and fit it to the 500 box. I haven't looked to see what drives the cable on a merc but on some other vehicles they use a nylon geared drive off the gearbox and they are interchangeable with drives with differing numbers of gears....
That would be the simple fix if that were possible??
Regarding fuel consumption, I'm pretty sure that's gone to pot but is of little concern to me as I m racing this car.
The speedo is now probably over reading by about 50% so I'm scared of breaking the speedo. In the interim I will simply disconnect the speedo.

  May I suggest the most simple way for speedo correction would be comparison via a GPS readout.If possible memorise or photograph the errors,disassemble the speedo from the cluster,remove the pointer (with two teaspoons opposite using even pressure) and re-fitting to make some sort of corrections.Don't expect corrections on full scale but you should get a better idea ot common speeds.Maybe you can drive the car without outer cluster outer connected and lightly re-fit the pointer for estimates around middle speeds? While the cluster is out consider a full clean,fit FLANKED LED's for lighting upgrade,or even white dials with chrome rings? How is your fuel economy now? RPM at highway speed?
