Look on ebay. It is pretty good for stuff like that. I have disassembled lots of speedometers and tachs, and they for the most part are built the same. Most Japanese cars (like toyota and honda) have gauges made by Yazaki Meter (including the volvo 940/960), Most european cars have VDO gauges, (like VW, Volvo, Mercedes Benz, and BMW). I just thought I would contribute my $0.02.
