National Output Shaft Seal for 1965-1966 T-10, 1965-1973 C4 and 1983-2004 T-5/AOD Transmission Equipped Mustangs.This is a direct replacement seal from National. This output shaft seal mounts to the rear of the transmission where the driveshaft connects. If your driveshaft slip yoke has fluid leaking off of it, you could need to replace this seal.
This will also work on Tremec 3550 transmissions.
