Speedo drive spindle in gearbox.

Hello Men,

I have a number of these and wondered how many teeth it must have for a 3.7 diff, its been a while since I rebuilt a box...Thanks in anticipation.

It really depends what calibration your Speedo has - i.e. TPM - and what size wheels.

There’s a calculator here which will give you the closest match for any specific combination
