Just today discovered that Bert's in Denver also has them listed for a much lower price ($150) than the others above:
A-2520-B BRAKE DRUM CAST IRON USA MADE 1942-1948 FORDS
The picture they show with these is the same generic one as shown for the 40-41's they show a different part number for. They're not open until Tuesday now when I'll try to confirm that these have the correct 4" center opening.
