This is the ultimate accessory for your Mustang. Scott Drake Rally Pac features a modern air-core movement tachometer and a quartz movement clock. Both the clock and tachometer faces feature the original style fonts but are backlit for improved visibility at night. The housing and bezels are pressure zinc die-cast from our own tooling and coated with a tough DuPont crinkle texture. Our Rally Pac's include all of the brackets and a color coded wire harnesses and easy to follow installation instructions.
