Age mice used for Allen Mouse Brain Atlas

I am trying to register reconstructed vascular corrosion cast data from postnatal mouse brains to the P14 (3D) reference atlas. I would like to use stereotaxic coordinates, that are available for the adult Allen Mouse Brain Atlas. Is there a way to obtain this “Common Coordinate System” for the P14 as well?
Link to publication of this Common Coordinate System:

The Allen DEVELOPING Mouse Brain Atlas has only an unannotated atlas, so far I can find.

Thank you!

We only built “The Allen Mouse Brain Common Coordinate Framework”, CCFv3 for the adult mouse brain, but don’t have 3D developmental mouse brain atlases. You can find our partially annotated P14 2D atlas of 39 sagittal views using the link (Interactive Atlas Viewer :: Atlas Viewer A group}
