67-72 A body bucket seat tracks.

I have a 67 notch and a 69 notch both stripped down to do restoration. Same floorpan both cars. AMD even lists the floor pan as all A body 108" wheelbase 67-72. Stamping changes in 1973 but its just positioning or elimination of reinforcing ribs.

Same floorpan under the 110" wheelbase cars like darts. Except *** end of the pan is longer by 2 inches. How do i know the differences? I used a 74 dart 4 door rust free man in my 67 barracuda. Fit just fine. Cut it 2 inches short at the back and put 1 non stock seam in it.
