Our father/son 1969 Mustang project has been sitting for more than two decades, so it's a foregone conclusion that the leaf springs, bushings, and shocks need replacing.

Most modern leaf springs use a rubber or polyurethane bushing in the rolled ends to help reduce road vibrations. The larger rolled end, known as the main eye, goes to a fixed point on the vehicle.

Additionally, the leaf spring from Eaton Detroit Spring was about -inch longer from the hanger bushing to the shackle bushing loop. See All 28 Photos The new leaf spring was fitted to the new shackle.
