Somehow I managed to lose not one but 2 of these gauges. The first one I loaned to someone, but that was about 15 years ago and it never came back. I bought another this past winter, and when I went to use it today, I couldn't find it. I searched all 3 garages to no avail but I did find some tools that had been missing since last summer. I am hoping that someone who has already purchased one and no longer needs it will like to recoup some of their investment. I will need the shims which I can get from my local dealer, but if you have them it will be a bonus.
