Rally Pac assemblies are the ultimate accessories for your early Mustang and feature both an air core movement tachometer and a quartz movement clock. Both the clock and tachometer face dials are designed with the original-style fonts, but they are back-lit for improved visibility when driving at night. The OEM-style housing and bezels are pressure zinc die-cast from Scott Drake's own tooling and coated with a tough, crinkle texture to ensure that these Rally Pacs look and feel just like the originals. The Pac kits come complete with all of the brackets, color-coded wire harnesses, and easy-to-follow installation instructions.
