Tichy USRA single sheathed boxcar question

Regarding Tichy kit 4026: What is the “doorstop” referred to in instruction #10 - “Trim doorstops at a 45 degree angle…”. ?

It must be one of the mouldings on the carbody, but the instruction is less than clear.

Anyone know?

Go to the Tichy website and get his email address. Ask him. I have done that.
