So i bought an after market tach because something is wrong with the factory one. I do not have the motor in car yet but need the tach for engine break in. the tach is to big to mount on stearing colum so I am looking for you guys to give some suggestions. And if you have pics of where there at in your car that would be great also. I had a friend suggest to take out the vent on the right and have a bracket coming out of there. I have no blower so it isnt going to effect anything. Here are some pics.
