Don't you just have to love how beautiful these Tach clusters look! There are draw-backs to them, and the Shelby had to overcome it with the SW Oil Pressure Ammeter setup. Cougar XR7 did a nice job too, using the same dash structure, but the Mustang "eyebrow" design overall, I think looks far better, notably in the 67's (but I AM partial, aren't I)
