More on the control stick length?

[hames57]

One of the sticks in my J3 restoration is 13 inches long, the other is 15 inches long. Earlier replies suggest they should be the same length. I'm trying to restore to original, so someone out there might make a measurement for me if they've got a good original restoration. It does look a bit goofy to have the different length sticks in the airplane. The shorter one looks more natural, but I'd like to know what Piper intended.

Thanks ahead of time.
