Leaf spring support
A leaf spring support used inside the gearbox inner cover and selector assembly.
57-4289 is a leaf spring support that lives inside the gearbox, on the inner cover with the selector mechanism. It shows up in the parts book under the GEARBOX INNER COVER AND SELECTORS figure, which puts it right in the works of the gear selection assembly rather than out on the case exterior.

The older form of this part number is T4289, the letter-prefix style used before the numeric system took over. In the factory records this part was later superseded by 57-4288, so if you're chasing this one down and coming up empty, that's the number to check as well.
Our catalog record for this one spans 1971 to 1972 and only turns up in a couple of entries, so we don't have a lot more to go on beyond what the figure title tells us. If you're not sure this is the exact spring your gearbox needs, give us a call and we'll sort out fitment before you order.
