All good
Swapped the LX series I tacho over. Removed the face from my grey, series II tacho (which had an ABS light as well). Existing series II tacho face had two screws holding it on, took the face off and the needle (thanks Rake!)... took the face off the LX tacho which was glued on (no screws). I just pried it off as I had no use for it.
Swapped the tacho motor bits over onto the grey face and clear plastic stuff, re-fitted, all good
I also used the clear plastic cover that sits over the instruments from the LX cluster, had to drill another hole in it for the HUD controls however, but worked fine and now the 'speckled' original clear cover is gone, replaced with a nice clear one!
Funny that the tacho and clear cover came off sleepa's wreck, that had 459,000km on the dial... still working well!
