Wanted: 30-U convertible top irons

[30-U]

I've got an early 1930 Plymouth convertible and the complete top irons are missing.
Any early 30 Mopar should be a close fit.
Drawings, pictures, sketches, measurements, xerox copies and or copies of parts are welcome as well.
Here are some pics of my 30 Convertible:
