From about 1914 through 1922-ish Ford used a metal trim along the bottom of the rear curtain where it attaches to the tack strip on both the touring and runabout.
Here is the rear curtain trim strip on a touring:
Here it is on Royce's runabout:
Richard Eagle made this sketch of the touring trim:
I have two extra trim strips for a touring and four questions:
What are the differences in length and hole arrangements between the two?
Can anyone proved details like Richard's for the runabout?
Can I cut down the trim for a touring to fit a runabout?
Does anybody have a runabout trim they would be willing to trade for a touring?

While we are on the subject, I recently had several rolls of rear window, and side curtain binding made of the correct T top pattern. It is 5/8" wide and is exactly the same as Ford used. Classtique is even using it. If you purchase a top or side curtains from anyone else, the binding will not be correct.
Keith, this may or may not help, but I am going to the Archives next month for a week. I can look up the drawing for you. I know they have the touring strip drawing because I looked at it and took down the dimensions. I don't know fur sure if they have the roadster strip but they likely do.
