Listers,
What's the thickness of the washer that is fitted between the gearbox
and the right angle drive (PN 3H550 or Moss PN 324-720)?
There are two MPH speedometers fitted to the 3000 MkI and MkII; one for
overdrive and one for non-overdrive cars. What's the speedometer
calibration (turns per mile) for each?
BMC P/N Smiths P/N TPM
non-OD BHA4124 SN6155/19 980???
OD BHA4126 SN6155/21 1080???
When fitting a 3.54:1 rear end to an overdrive equipped car, does the
non-OD speedometer have the correct calibration? I think that it would
if the gear ratios for the speedometer takeoffs on the extension housing
of the non-OD gearbox and on the overdrive were the same. If not, what
calibration (TPM) have folks used?
Cheers,
Bob Haskell
