From what I got out of the guy that I purchased the 4 speed conversion parts said it came out of a '72 Duster 3 speed on the floor. The small block biscuit k-frame that I also got from the guy supposedly came out of the same car. It has the washer welded to the front. So my guess (I never actually saw the car sense he towed it back to the scrap yard :( ) is that it came out of a Red (floor hump was red), '72 Duster 340, 3 speed on the floor. :(:(:(
