One source for 6v tachs is http://www.westach.com/products/SINGLE/2%20INCH/TACHOMETERS/index.php

To use a 12V tach on 6V you need to also change the internal lighting bulb to 6v. Really best to get a 6V tach.

Most aftermarket Tachs also have a selector for number of cylinders that needs to be set.
