Ford started to use this slip yoke in production early in 1970 to replace the earlier Ford-machined inner u-joint cup cut version. It would be concours correct for a Boss 302 or 351 Mustang because it’s a Ford production slip yoke. Ford stopped servicing this slip yoke years ago. Therefore, they are now only available NOS or used. Once installed, the late service version looks just like this one, except the slip section of the yoke is shorter.
