[Healeys] Speedometer

Strange.  Unless they used a different gearset in the O/D the rebuilds 
shouldn't have caused this.  I believe the angle drive uses a short 
wound cable similar to a short piece of speedo cable.

If it's high across the board you can calibrate it yourself.   Remove 
the speedo from the panel, 'unscrew' the bezel and gently prise the 
needle off (pull straight out).  You'll probably have to set it under 
the peg, which is spring loaded so you can rotate the needle past it so 
it can rest on the peg when stopped.

I use this site to calibrate:
