If the engineering drawings survived, you can obtain copies of them for your side curtains from the Benson Ford Research Center in Dearborn. You will need the part numbers, which are in the '32 body parts catalog. (Please let me know if you do not have a copy of that catalog.)
If you cannot find someone nearby to make your curtains, Jay of jljohnsonupholstery.com in Hartville, OH has photos and dimensions of an original set of '32 deluxe roadster side curtains and the only difference is the cloth material color and the absence of provision for a post-mounted outside rear view mirror in the standard curtains. You will need to provide paper patterns to locate the various fasteners on the curtains as there is sufficient variation in the fit of top bows and irons relative to the sockets in the doors to require some customization of the fastener locations.
