No clue. Personally, I would rather have a smaller tach, not a 5". I guess you could make a bracket to your dash. Or, I think this is a good idea, but dont know how it'll fit....mount it above your radio bezel, above the vents, on the dash. You'll need to take out your radio, the bezel, and maybe some other misc stuff. I'm familiar with the Auto Meter Monsters, so you dont really need a flat surface to mount it. Try it out, let us know. Keep in mind, holes in your dash is an unfortunate must.
