I just buaght one of those moon tachs off ebay, i didnt want to buy from moon becuase i tried to get something from them years ago and had to send about 15 emails for 3 weeks before i got a reply and the reply was kind of nasty, it was then i picked half the moon sticker off my 1/4 window, they have some real fruit cakes working there. Anyway the tach looked ok in the picture, i thought it was like a remake of a old dixco, i didnt want another old tach becuase they dont seem to last on modern ignition systems so i bought this new one. Anyway it arrived and i took it out of the box and it looks like a real nasty cheap crappy peice of junk compared to a old tach or any tach but even worse it has some butt ugly big hose clamp to hold it onto the colum and this was wrapped around the cheap chrome plastic tach housing and had left all deep scratches in the housing. so before i make a bracket from alloy that screws to the top of the colum and drill hole in the colum, are these worth using, do the last and are they accurate? i have crane hi6 ignition.
