Of course this is an opinion (mine)

I've seen the visors on Model A's with 1 to 2 inch holes in them and really don't care much for them. Is your car is a going to be 'rat'(I don't think so), then that might be different. Do you have that visor off now? If so, make up a similar cardboard version and see what it looks like. That's one Model A part that repro replacements have not been well made though I have seen homemade versions that are barely OK (now if you had a slant windshield '31 Fordor, it wouldn't have a visor)
