9721-2 Motor mount spacers

These Colony motor mount spacers are a specialized solution for 45" Sidevalve owners. Designed to fit 1937 to 1973 45" SV models, these spacers are used to correctly space out the two longest head bolts, ensuring proper alignment and tension within the motor mount assembly. They feature a traditional parkerized finish, making them ideal for restorations where a factory-correct appearance is required. Colony manufactures these to precise tolerances, ensuring they fit perfectly over the head bolts and provide a stable mounting surface. Using the correct spacers is essential for preventing stress on the engine cases and maintaining the structural integrity of the drivetrain. These spacers are sold as a pair, giving you exactly what you need for a standard installation.
