Well I guess it depends on what everyones idea of what "looks like it belongs" is.
To me that means the factory tach. Which is why I'm sending mine out to have it refaced in original faunts for a higher reading and then recalibrated.
It's expensive to do, but it will look correct when it's done. Most people probably won't even notice the rpm change on the face.
Until then I just mount an aftermarket on the column, old school style
