been thinking of an electronic speedo conversion for the Ninety, it' 'origonal' speedo is in km (as an ex-Army Landy) and
interesting when accuracy is concerned
theres a few manufacturers of programmable electronic speedometers like Stack & VDO and also unbranded on ebay etc.
subject of ebay, looked @ VDO as they're similar to the origonal 80's LR items and there was one advertised as a tachometer (but photos of a speedo) for sensible money so some bidding followed
delivered today and it's a speedo so happy-days
the millage may be resetable, will have a read of the distructions
came mounted in a dashtop 'pod' and pre-wired, live / earth & signal with the live & earth bridged to the illumination, I'll probably keep this as such (K.I.S.S.)
p/number etc. the mount-rings are available seperately and Merlin Motorsport have stock

this speedo is programmable and accepts various pulse inputs (& 12 or 24v power)
distrctions are online

I'm thinking of fitting a 'hall-effect' sensor in place of the old speedo-cable on the transfer box to generate the vss
ALSO...
I think this speedo supports a vss output so options for fitting cruise-control
more on the joblist
