Roland,
The Tiger Speedometer is, maybe, different from a Cobra. Firstly, even
though it is an English speedometer, the cable attach is American style,
not normal British, so the Ford cable can be mated. The cable is
American size because of the speedo drive gear.
The internal speedo gears are all British, don't you know, and not
plentiful, or cheap. American speedometers have a distinct commonality.
They are all set to be 60 mph at 1,000 revolutions. The transmission
teeth are selected to accommodate that standard for the rear end and
tires of the car design. Any modifications are usually handled by a
change in the cable end drive gear.
Not the British. As pointed out, the speedometers can be labeled "980",
"1020", etc. The Alpine O.D. speedometers are particularly odd. All
american speedometers are "1000" by standards.
Bless the Empire.
Don't know what's inside the Cobra, but if you've been able to put
American inner pieces into the works, you are fortunate. The rest of us
are stuck with the high price solution. Additionally, unless you want
"1000", the American gears will give the wrong calibration, even if they
did fit.
