The top corners are definitely more more rounded than the lower ones on the '32 garnish, but don't think there's a whole lot of difference in the curvature of the upper and lower edges themselves.
There are probably two different ones. The 5W coupes have two different door and back window moldings. They changed number and locations of the mounting holes. For instance, the door moldings come with either two or three holes on the inside front flange. Other holes are different as well.
sedan and coupe are the same shape sedan 3/4 and coupe 1 1/4 thick-- bottom corner is tighter than top arch (yours looks like maybe 31 vicky shorter but taller)
