The Ford heavy duty Top Loader 4 Speed Transmissions were, and may still be, the toughest and most reliable manual transmissions ever built. 

A select few of the Top Loader 4 Speed Transmissions were stamped with the matching vehicle VIN number.  This happened with the Special Edition vehicles (Shelbys, Boss vehicles, Eliminators and K-code Hi-Po Mustangs)

In 1970, Ford began installing Hurst High Performance Shifters on Top Loader 4 Speed Transmissions, mainly in special edition high performance models.  These Hurst Shifters were an upgrade to the stock Ford shifter and featured quick shifting, short throw shifters that were used with Ford heavy duty shift linkage.  This powerful combination achieved a quick shift engagement. 

In 1971, 1972 and 1973, the Hurst shifter was used in the Boss 351, 351 CJ, 351 SCJ, and 351 Cleveland H.O. high output engine.
