I don't know how knowledgeable you are, but the serial number for '32-'48 Fords is actually stamped in the top front of the transmission. Thus, the chances of finding the absolutely correct transmission for your car are virtually nil, as it would have to be the original that came with the car when new. Thus it is a good thing that you are looking for a "period correct" transmission. They are out there and not than hard to find. Anything from '40 through '48 (Ford or Merc) will work, thought you may have to change the rear mount depending on what you find (you already have the correct mount in your car if the new transmission has the wrong one or it is missing). If you are not attached to the floor shift transmission already in the car, you should be able to make the change for little or no out of pocket expenditure. (You may even be able to make a little on the deal, as more people want the floor shifts than the side shifts). It all depends on condition, however.

Hopefully the shift rods from the column to the transmission came with the car. If not, you'll need those too, plus maybe some other linkage parts and bushings, etc. Everything is available, though.
