The Goodson Double Harley Head Plate takes the universal design of the company's HHP-6 Head Plate one step further to accommodate two heads at the same time. Due to its unique mounting system, it fits Shovel, Evolution, Twin Cam, V-Rod, Sportster and Pan heads. The plate is heavy enough for cutting and installing guides and seats, and is designed to be used on a seat and guide machine or Bridgeport-type Mill, including CNC machines. Mounting instructions (with diagrams) for all head types are included. Blackened steel construction.
