Anyone got any pointers on where I can get a tacho from without spending a bomb? It'll probably be stuck out of the dash somewhere, as there's nowhere to fit one in the instrument cowl thing. Transplanting the instruments from another Ka looks like it might be difficult as the ones with rev counters also have digital odometers.
It needs to be pretty big, backlit if at all possible, 0-6 or 7krpm should do it. All the one's in demontweeks are £100 or so (too bloody much).
