It could be for a Dagenham trans, Ford lopo cars used them. This may help I.D. it. https://www.google.com/search?clien...HcxlDqcQ0pQJegQICBAB&biw=1280&bih=800&dpr=1.5
Not a Ford guy but it appears the early 60's Fords used the "T" style for reverse lockout but some of the later 60's did not use it.
Four-speed with a three-speed lever.... Ford used the same shifter ***embly for both the T10 and Toploader, just switched the trans levers and shift rods for the specific trans use. All Ford-built four-speed shifters had a reverse lock-out, the early ones used the 'T' handle, the later ones a sliding knob. There were also three distinct mounting brackets. Front mount for the '63-65 Falcon/comet, mid-mount for Fairlanes and some full-size, and rear mount for the Mustang and some full-size. The one pictured is a rear mount.
