What's the difference between these wheels?

Well, good luck! The 4-1/2" wide '42-'48 Ford 16" wheels are still easily found today, and should be quite abundant in your area of California at some of the old Ford parts emporiums. But, like I indicated yesterday, those '41 Mercs aren't growing on trees, and they NEVER did. In my playing with this old junk for well over 50 years now, I have never laid eyes on a real pair of 5", '41 Merc wheels!

Just for reference, 4-1/2" and 4" on this Florida 3-window coupe. DD
