another breakable item that's easyly fixed is the pin that the pointer rests on, like on my truck the tach would almost point straight down when off, i just heated a needle and stuck it in where the orignal pin was. and for some reason the trip reset button was missing, i made a new one from a piece of plastic rod a bench grinder and a drill, if you cut a step in it where it pokes through the clear plastic it will be held in place
