Technical 1932 top iron question

Buddy of mine has a 32 Ford Roadster, ( I know, lucky SOB), and wants to know what the difference is between 30/31 Model A Roadster top irons and bows and a 32 Ford Roadster top irons.

Can anyone enlighten us?

We used an older repop top on our 32 - see link below - and were told it was for a 32. Chopped it 3" and added new fabric.
Don't know what the differences would be between the 32 and the A. If the top bar (wood) fits the windshield posts and etc. you might use an A. Especially if you fit new fabric...
Check the folks at Lebaron Bonney who make these things...

 

This is from Le Barron Bonney. Note slight differences. 31 on left, 32 on right.
