Not all 31's have the indented firewall.that was a Mid Year change

A lot of mid 30's had the round speedo

Some States issue numbers that have nothing to do with the Ford numbering system ,

Especially if the owner built it up from parts without a title.

Has it got the long splash aprons by the running boards or short ones with the nose piece on the fender?

hope this helps
