Identifing a 28 roadster top

[Mountain Dew]

I recently bought a driveable 28 roadster with a paint job and bells and whistles but a low quality restoration. I want to do a correct restoration. I think that the top may be a 30/31. How can I tell the difference between 28/29 top irons and 30/31 top irons?

Width and height.

Give Lebaron-Bonney a call they are good about helping A'ers.

Also, to make maters worse, going from memory, there are 2 different tops for
the 28-29 roadsters.....Marco knows....should have written it down.

It seems like the 28/29 ones had tapered tubing and that later 30/31 ones don't.
