That's a yes Weggy.
The box must be in neutral and the dots lined up, then fit the outer cover and secure with just a couple of the nuts, next see if all the gears can be selected, turning the wheel with your hand as you work the gear lever, if all's well fit the rest of the fasteners, sometimes you might have to align the dots slightly off one way or another to get all the gears, my Flash box works with the dots lined up but the rocket needs the selector dot one notch lower.
