Tired of using wipe on type materials to display your dial-in? We've designed a Velcro mount system for the side window of your door car or a Bolt-On billet scoop mount unit for a rear engine dragster with the JEGS scoop tray (sold separately). The bolt-on board mount is fully polished and then chrome plated for a show car appearance. The mount features a full 360º adjustable swivel for facing the tower from any direction, includes stainless fasteners and measures just 14" long x 7" high overall. Each style of number board measures 10" long x 3.5" high while each number measures 3" high x 1-5/8" wide. The dial in is easily changed on all boards by simply flipping a section or sections to achieve the optimal advantage. Made In USA
