35-37 back of cab bracing help needed

[Model51]

Attached is an image from the 50-813152 Ford Engineering Drawing from 1935 showing the part you are asking about. It's straight except for a short section on the bottom. Hopefully you can figure it out as it's a bit dark and is just a small section of a very large drawing.

This support has anti-rattle material between it and the back of the cab and so does the roof support rib(s). I used Dyna-Mat to insulate my cab and slid this material into the gaps and it works just fine.
