And that would pretty much bear out what the numbers said. Dakota front track around 60", early 40s Dodge trucks almost 56", that would be 2" less clearance per side. Using the Dakota offset front wheels would have probably allowed a wider tire on the pictured truck, because even the front runners look to be the standard offset.

The truck fenders are pretty big, I suspect a guy could gain a couple inches per side with a little customizing of the fenders. Wouldn't be the first time fenders were modified for clearance.

Another thing you need to keep in mind is that after WWII vehicles selling like hot cakes, I suspect more emphases was placed on getting them out the door then was placed on the vehicles being spec sheet correct. That could mean things would clear on one truck, but maybe not a different truck off the same line the same day. Gene
