As Kirk says, the 37 Ford hubs look just like the 9N/2N tractor hubs, but the bolt circle is 3/4" different. Car hubs have a 10.5" circle and tractor hubs are 11.25". Not enough of a difference to spot with the naked eye but you find out quick when you try to mount car rims on tractor hubs.
Fortunately the car hubs fit the tractor spindles without any modification. I used to have a photo of what it looks like when you try to put a tractor wheel on a car hub, but apparently I haven't logged into my photobucket account in a long time and it's been deleted.
