i ended up using a defender gear.. in t case. D1 short cable to speed transducer..... and nas spec top part which was ludicrously expensive for a cable... but itfitted and worked. The oy other isdue i found wasthat the discovery and defender appeared to use different size square drives on the short cable.... so i got speedy cables (not very speedy!) To make an inner with the bigger square on it....
You may find that with the 98 being i guess a serpentine front... it might have the electronic speed transducer on the transfer box... quite how people get round that im not sure.... probably just replace it with a full cable and ignore telling the ecu you'r moving.....
