Here's what I was driving when I saw Ron Courtney's shoebox Ford on the street in McMinnville, OR. I know Studebaker and Ford had a similar cowl width; it looks like Mr. Roussell didn't have to shrink things much to fit the Type III.

In the 1980s there was a famous topless Squareback show car (the underbody was painted with scallops to match the topside) that had a chopped Type II windshield (with Safari windows). That would pair well with the bullet nose.
It works the other way too. I held a Type III windshield up to my panel van and the width was perfect. The top would tuck under the roof and block or eliminate the ventilator. It would be a not-bay window.
