Donor wheel options for 1937 Buick

I would like to use traditional style painted wheels, poverty hubcaps, and trim rings on my 1937 Buick Roadmaster.
I want to run radial tires that are either 205/70R16 or 205/75R15 because they will be compatible with my drive train.
I've found numerous Buick dog dish hubcaps that vary in size with inner diameters of 7.75, 7.875, 9.75, and 9.875 for different year .
1) Can anyone recommend a modern 15" or 16" wheel with a 5 x 5 bolt pattern that one of these hubcaps will fit?
Thanks
