This is the most popular shaft that was produced for most of the late C4 & C5 351W 351C


The early model C4 (1964–1969) used a .788-inch 24-spline input shaft, which was upgraded in 1970 to 26-spline and .839-inch. The upgrade also included a matching clutch hub of 26-spline. In 1971, Ford went to a .839-inch 26/24-spline input shaft, meaning the torque-converter side is 26-spline and the clutch hub is 24-spline.
