the mount on the base plate easier.

This is one of those times a digital picture would be a 1000 words.

On the AP website you can see a drawing of the top
of the pier, for a 900, with the base plate attached.
Click on "mounts", then "pier accessory tray".

If you look at the photos and drawings of the 900 mount,
the base plate is attached to the mount. However, that plate is
shipped from AP attached to the pier. Same for the 1200.
