The standard dash tacho on rangies is driven from the alternator, so the engine that's fitted shouldn't matter in the slightest. Drive it from a TD5 alternator and it should work although pulley size differences could give you an error. Mates with V8 RRC's have found 10% or so difference in tacho readings after an alternator swap.

Failing that. My tacho had already been butchered to work on DC, I made up a little frequency-voltage converter. It's quite simple to make, I bought a little chip and hooked up about 6 wires with a resistor and trimpot to tune it.

There's no point trying to fit a disco tacho to a county, the disco info was for the benefit of the disco and rangie owners reading this thread.
For the county a standard 52mm gauge driven off the alt would make the most sense.

I second that - probably the simplest way if you already have the pulse wire installed

Guys im still looking, seems that the standard 52mm tachos are becoming extinct. i would like some thing that will sit beside the speedo on my extended pod and look like it belongs there.

For a 52mm tacho, you can try E-bay. Although they seem to be alot of "no-brand" chinese units.

For my Rangie, I ended up going with the VDO. Looks about similar to the smiths gauges. Not cheap, though.

there only seem to be digital tachos for diesels on ebay

VDO still do a 52mm tacho - here's one:

The picture shows the 0-7000 RPM one, but it's also available with a 0-6000 RPM range more suited to a diesel than the 0-7K or 0-8K ranges.

Here's a cheaper 52mm tacho that is available with a 0-4000rpm scale:
