Replacement Voltmeter ?

[Adrianw]

Hi,

My voltmeter has decided to play up and I would like to source a replacement ,
does anyone have any ideas where I can get one ?

(Dan T has removed and checked the voltmeter and confirmed it is over reading by 4 volts which put it off the reading scale, could get it repaired by turn around seems to be 6-8 weeks , can't live with the hole in the dash that long )
