Dial-in Boards designed just for door cars. Change your dial in quickly and easily from the drivers seat while you are strapped in. All the flexibility of an electronic board at 1/4 the cost. Installs in 5 min. to the halo hoop of your roll cage with only a screwdriver. Complete with all mounting hardware and FREE SHIPPING to your door. To set or change your dial in simply rotate the board 90 deg. to face the driver, flip the numbers to your new dial in, and rotate 90 deg. back to face the windshield. It's that fast and easy and the unique mounting bracket locks in place automatically in either position. Message, call or text Vince @ 440-487-4861 for more information or to order. Thanks.
