The 289 cars used the galaxie transmission as the shifter is mounted well forward. It came out in a perfect location, but they had to make the stubby straight shifter for it as the others were too long. When Shelby started stuffing in the 427, they needed a shorter transmission, so they went with the Mustang unit. The problem is that the Mustang unit puts the shifter at the end of the tailshaft. Flipping the Mustang lever solved the problem.
