            ignition The street legal XR700 is the ignition that made Allison famous.
            Now by Crane-Allison, development continues to keep the XR700
            on the leading edge of ignition technology, giving you increased
            performance, better mileage, and easier starting. Installation
            is simple, and distributor tune-ups are eliminated forever. Triggered by Crane-Allison's patented optical system, the
            XR700 is the world's most popular most popular ignition for modernizing
            point-type systems. An L.E.D. emitter-detector replaces the stock
            points in your distributor, and the solid state control box is
            mounted nearby. Legal in all 50 states, the unit carries a limited
            lifetime warranty, and is transferable to another car. (If a
            worn, wobbly distributor shaft is causing erratic ignition, installing
            the XR700 will cure the problem).
