WILLl f body auto floor shift and console fit a 73 to 75 duster ?

Make sure you get ALL the parts for it!
Floor brackets; all linkage including rods, pivots, transmission and frame brackets, all console wiring (and as long of the connecting pigtails to the main harness as you can get, making careful notes as to what circuits it taps into), take careful measurements as to where the floor brackets attach (and photos) and where the linkage goes through the floor. Heck, if practical I'd take the whole transmission tunnel with everything intact...
