I've used a Hall sensor type speedo sender from some Ford, probably a Mondeo. The sender gives 8 pulses per revolution, it's mated to the speedo cable port on a Type 9.
The speedometer cables used to be calibrated to 1000 revs per mile or some metric approximations. I just set my speedo to 5000 pulses per km (ie assuming 625 revs per km or 1006 revs per mile), and my speedometer reads well enough, without a significant discrepancy to the phone GPS.
Are you using the gearbox with the final drive that came from the same car?
Hope this helps!
