Here's a side pic. I think I flipped the metal mounting bracket upside down and have a rubber ring underneath the zip tie so it doesn't slip. Now that I think about it, that mounting bracket might be from the previous 2", 6K Autometer tach. I had.
I wanted a non permanent mount.
Autometer, Ziptied. I like the 4k limit and it's lighted.
The straight on pic is misleading, it only blocks the blue high beam light in the gauge cluster from the drivers view.
