p.s i'm using a jag type zf box.[/quo
Sounds like a lot of work to fit a speedo drive worm in the tailcone of the Jag, I am not saying it cannot be done, but it does seem a long winded and expensive option, especially if you have to employ the services of a machine shop.
As Warren suggested, the Dakota digital kit is a very good option, and is a straightforward fit.
If you go ahead with the speedo worm option, then you may have to trim a little off the output flange, so the speedo worm fits on the output shaft, the drive worm would also need to be modified, as the BW 35 drive worm splines does not match the ZF splines.
All doable, but time consuming and costly, you could also use the range rover lower speedo cable, as this has the option of fitting cruise control or other electrical options that require speed inputs.

Give me a bell when you want the speedo, 'taint going nowhere.

fylde69 said:thanks for the input folks, i'll agree the Dakota option is the most sensible option all round apart from the cost. easy to fit and as proved works well.
however i am fortunate enough to have access to cheap machining through work and i like the challenge i'm going to carry on with the options I've got so far....(then probably buy the Dakota anyway )

Well if that is the case, then the world is your oyster, if we can put a man on the moon, you can fit a speedo drive to your tailcone for sure.
There are drive worms available to fit your ZF output shaft, but they are rare now, and you would still have to overcome the cable drive side of things.
Interesting stuff.
