Dodge made 2 different cabs in 55, an early one with straight, but angled front door posts and a windshield that did not wrap around. The late version has dog legs in the front door post, and a windshield that wrapped around the corner. I suspect the late 55 will probably work with the 57 nose, but I would be really surprised if the early version did. I'm posting a picture of my 54, that has the same cab as the early 55. Take notice of the front door posts, its the easiest way to tell. The change in the cabs took place in March or April of 1955. Gene
