Hi Ford Only
As I felt I had explained, after dismantling the speedohead, cleaning, rebuilding and refitting and connecting up a new cable, I verified that the 'system' thus far was 'fine' by spinning the bottom end of the cable from under the car with an electric drill and got good steady readings up to circa 90 mph. The problem lies at the interface twixt cable bottom (driven) gear and 'drive' gear on transmission tail shaft. I suspect they are not engaging properly and would like to know what the correct pairing is for my spec. car so that I can have them to hand when I dismantle transmission to do the repair to avoid long off-road delay.
Somewhere that information should be available, surely??? - but I don't know where to look.
Many Thanks
JK
