DC-3 Airliner

I am building a DC-3 from Revell.  The interior is more the C-47 military interior.  That does not work for an airliner.

I have marked out where the seats go, next to a window.

Early models had two rows of seats, later models had three rows, one on one side of the plane and two on the other side of the plane.  This will be a two row plane.

Here is how it's supposed to fit together.

I will need to add some angle iron plastic to make the civilian seats.
