Won't work because the '60-'62 use a completlely different axle than the '63-'64. Used to see the same thing on the Summit site on Posi units, exept they go to say that it's for " '62-'76, 30 spline only". The 30 spline 12 bolt was a midyear introduction in '65, and the '62 is a different axle altogether.
