i was able to get my VDO gauge to work without using it, so it's BRAND NEW with all the pieces and literature.
comes with the 6mm transducer.
looking for 80 shipped.
morning bump... i'll take offers.
Man I really want it, but my wife doesn't want me to spend anymore on things that aren't a nessesity. I don't want to lowball for such a nice piece either. If you still have it come fall I will probably end up with it
like i said i'll take offers into consideration
I've never seen sucha tiny tach

Maybe i'll find some grey window cranks to trade with ,,,,
haha, i never thought something so silly would be so hard to find!
Out of curiosity, has anyone ever used one of these and are there any opinions?
And would a 1.6NA use the 6mm or 1/4" transducer?
