Good looking and functional product. My dash is 1-1/4" thick so I had to cut the clamping ring ears off to achieve a secure mount. I expected a problem, so I was not suprised. The terminals on the tach itself were designed for the spade type and since my old tach had the screw type which required new terminals to be installed on my existing wiring, again no problem. The actual hook-up was then very simple, easy and straight forward, the new tach is working perfectly.
