145.012 Movement Holder installation order

Hello OF!

I am currently putting a 145.012-67SP back together and now have all the parts to do a test fit. I am bit of a loss trying to use documentation and various images around the net to understand the order of operation on reassembly. The movement holder I have is with holes rather than notches to allow the movement holder to be just dropped in with the Start/Stop & Reset Stems attached (1757A&1758A).

I'm gathering that I need to install the start/stop lever (1720) after putting the movement into the movement holder as the direction the post on the lever is opposite of the direction it is installed into the holder. Am I missing anything here? Any info/help would be greatly appreciated!

As a follow up with maybe some more clarity -

Here is an example of some process photos of a 145.012 disassembly (with the same through hole movement holder). The movement holder is seen removed early on and with the pusher stems seen still attached as well as the 1720 lever.

This example does show the movement holder still attached until the 1720 lever is removed which seems to me what is required to assemble/dissemble the watch.
If removing the lever is required - I have seen a few variations of which parts are removed to get to the 1720 lever. Would anyone mind shedding light on to the order & proper parts to be installed/uninstalled when interfacing the movement with the movement holder.

Thank you!

Thank you Archer! I attempted this first, but the angle at which it needed to go in spooked me and put me into a pause. Now with some confidence and knowing that it is the proper order of operation - it went in with out much of a fuss. Onward!
I very much appreciate the comment.
