so i cant use the 71-73 mustang seat latch, they didn't fit on my seat, that why I don't think are even mustang seat cause the seat hinge is difference
The change on the seat latch from center to outboard went into effect on 6/15/71. The Pinto and Maverick with bucket seats were also involved in the change and share the same latch components. As always when dealing with mass produced vehicles there will be some fuzzy areas on vehicles built right before or right after the change date.
Don @ Ohio Mustang Supply sells the plastic hinge covers and the chrome knobs for the 71 center latch and the left and right outboard latch for the late 71 and 72-73 Mustangs.
