Need help ID'ing Model A sedan to truck build parts

I bought this cab on Saturday morning. The seller wasn't super knowledgeable on it and had thought it was a '29. From what I know about Model A's it's is my belief that it is a '30 or '31.

This cab was built from a sedan at some point in its life. I'm trying to understand exactly what year car it was assembled from. I'm also curious if it was built from a tudor or fordor sedan. I'd like to know so that I might be able to order some pieces I need to help get it back into shape.

Here are a couple of photos I have of it.





Thanks in advance for any help.

the cowl is 30/31

 

The farmers here in the central valley of Cal, did that alot, your is a 30-31 made from a tudor sedan body, all 30-31 parts will fit except maybe the seat frame

 

Thanks much, fellas!!!
