This is a NOS Ford flawless correct original 4 speed shifter boot which is correct for all 1966 1967 1968 Mustang and Shelby cars equipped with the original Ford 4 speed shifter.   It is correct in every detail with the original Ford engineering number cast into it.   These are reproduced but the repros are really crappy and do not even resemble this correct NOS part.   Would look great on a  high end show car like a Shelby or HIPO.
