just my 2 pence worth - my car had the digital clock and it worked when it wanted......and to me it always looked a bit naff......so I bought a set of clocks with the old analogue style in ( and as we all know these old analogue clocks never work due to age and rusty internals ) so I removed the clock face and gutted the workings but kept the clock support frame that screws into the clock pod and 'by the power of ebay' got a clock from an old ford ( these have plastic cogs ) and fitted the Datsun face over it, glued it into the clock pod....
Simple, cheap, job and the end result is a nice, original, looking analogue clock that keeps good time.
