Given your objective, your best bet by far is to locate someone near you with a bare body of the type you wish to create who is willing to let you measure and photograph it for your purposes. I'd call that Plan A.
The original engineering drawings for the parts that compose a '32 coupe (there were three different ones, so you'll need to decide which one you want to create) exist on microfilm at the Benson Ford Research Center in Dearborn. They can provide you with restricted use copies for a fee. The fees vary depending on the form of the copy. The least expensive are paper copies derived from microfilm readers, but due to equipment limitations, the copies are limited to a size of 8 1/2 x 11. As many of the drawings are full scale or half scale, you can imagine how many different overlapping copies you'd have to make in order to create a whole drawing of say a quarter panel.
They also offer CD copies which while way more expensive are at least of the whole drawing.
In order to obtain any copies from the BFRC, you need to know the original part number of the part drawing (blue print) that you want. Some of those numbers are contained in the '32 body parts catalogue (readily available as a reprint). Unfortunately for your stated purposes, the only part numbers that appear in that catalogue are those for parts that were available for service. As often as not, that service part was not a single component, but rather an assembly or sub-assembly. For example, there's a part number for a coupe deck lid in the catalogue, but quite possibly there's no drawing of a complete deck lid, but rather a list of the parts and part numbers that are the constituent parts of a deck lid. Those part numbers are the ones that will lead to the drawings of those constituent parts. I'd call this Plan B.
You'd be faced with an incredible amount of hunting and sorting through microfilm images to get to what you'd like copies of for your project. (For a task of this magnitude, the BFRC is not sufficiently staffed to do this job for you.) You'd have to spend some serious time on site to do it yourself. While this process will be an education in itself, you may end up regretting not pursuing Plan A, especially once you've totaled up the cost of Plan B in terms of both time and money.
