Atlas 2 Speedometer Gear

Looking to confirm if the circled notch is the selector for the geared teeth. I installed a 35 tooth speedometer gear just want to make sure I’m dialed in correctly.

In addition will the VSS from the Dakota Digital VHX function accordingly with the Atlas 2?

The VSS adapter will work fine. As for the installation, for many decades, same Speedo design Chrysler has used since the 60’s, I use a small screw driver to turn the Speedo gear and check that it is engaged. then rotate the housing using the retainer as a tool until it won’t turn further then back up until the retainer fits. If in doubt here’s a YouTube Link

Tooth count positioned at 6 o clock?

Not all applications are clocked the same. The output gear housing is eccentric to accommodate different diameters of gears. with the different clocking is why I use the screw driver to verify engagement of the gears and rotate the housing to the deepest possible engagement that allows the retainer to properly engage the housing. I believe the addition of the gear tooth numbers to the housing creates more confusion that there is something to align, when there may or may not be.
