Speedo cable ratios LT95-LT230-Series TF

[Lotz-A-Landies]

Further to Steve G's question:

Does anyone know that the speedo cable ratios are in relation to the various Land Rover transfer boxes: LT95?
LT230?
Series Transfer box?

Am interested to know if I can use a standard series speedo on an alternate transfer box.

I don't know about the speedo end.
I take it you already know about the different coloured drive gears that have different numbers of teeth? So you can change the drive gear to get a different ratio...

I found this list the other day while looking for other info:

90/110 speedo drive gears
frc3310 blue --------- 20 teeth
frc3311 green ------- 21
frc3312 yellow ------ 22
frc3313 red ---------- 24

Discovery 1 [200Tdi/V8]
frc3310 blue ------- 20----diesel
frc9339 ------------- 23

frc3310 blue ------- 20 ---- V8 efi
frc9339 ------------- 23 ---- V8 twin carb
