Rearview mirrors for 1931 S/W Town Sedan (160B)

[rivcokid]

Has anyone with a 1931 S/W Town Sedan been able to get rearview mirrors for the sides? Whenever I look them up through the parts dealers, they have hinge mirrors and clip mirrors that all basically say that they will fit any enclosed Model A EXCEPT for the S/W. Why is that? What have you been able to use? I'm going to need to have some.

Thanks, as always, in advance!
