I bought a pair of white faced Veglia clocks as fitted to early V11s with the idea of fitting them to my 05 Le Mans replacing the black plastic ITI things, after changing the wiring plug on the tach and changing the speedo cable, it has a smaller top connection on the ITI and fitting the angle drive from an earlier model, yes it all worked until I went down the road and the speedo was reading much too high, further investigation and cursing revealed the worm drive in the gearbox is different, I do have both gears in stock but I draw the line at tearing the gearbox apart, so be aware that the later speedo cables spin faster than the early ones,
at this point I put it all back as it was.
