A 1966 Mustang typically fits a Ford 8-inch rear end or a Ford 9-inch rear end, which are both popular options for upgrades. The 8-inch rear end was standard in many 1966 models, while the 9-inch is often chosen for its strength and durability, especially for performance builds. Additionally, some enthusiasts may use rear ends from other Ford models with modifications. Always ensure compatibility and consider the desired performance level when selecting a rear end.
