According to the 1930 - 1939 Hudson Master Chassis Group Parts Book that I have in the online library frames are pretty much year to year for each make The 1932 Essex frame has part number 37200 for LHD and C 37201 for RHD. It's probably possible to adapt another year with the same wb (113") but I don't know how much work would be involved.
You can check the manual at the online website @
http://hetclub.org/burr/lithomepage.htm - this manual came from another source so is not searchable. One of these days I'm going to print the thing out and rescan it my way.
In the meantime the frames are in Section G, page 145.

Guy, you have put this message under the "Club and Forum -- Suggestions and Comments", where practically no one will read it! We'll move it down to the "Hudson" area (which covers pretty much everything under the sun, except Club business).
