Hi, John, Just a quick email to thank you for the re calibration work you carried out on my speedo. I put the speedo back in the car this morning and have just returned from a trial run.
What a difference it makes to have a speedo that reads correctly! Thanks again for a superb service and quality of work Best Regards.................................

John, Just wanted to confirm safe receipt of the re-calibrated TR speedo on Tuesday (it arrived just after we spoke!), and to advise that it worked perfectly on the test
drive into work  this morning - it is less than 1% different from the Halda, which is about as perfect as it can be! Many thanks. Regards.....................................

John, thanks for doing the upgrade on my Triumph TR rev-counter I thought that after fitting the 123 Electronic ignition I would not have a working rev-counter,
I had of course considered fitting a new unit but its far better to have the original unit working & looking exactly the same ... Brilliant ..Regards........................... ..
