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

Thanks! I really appreciate site you and all the wisdom. This is my first 30's ford so I don't know much about them. I just spoke with a gentlemen and I'm
Buying a set of the 4 1/2". I would really like to run some divco milk truck wheels in the back but those are just a rare as the 41 Merc wheels I assume.

Are you running radials on yours?
