1940 3/4-1 Ton express frame measurements

[GB SISSON]

I have a bare rolling frame from a '46 tonner amd a couple of complete 47 tonners here. I also have the back half of a '39 tonner that was made into a trailer for a welder. I know the axles changed width with an increase in '42 of 2 1/2". Would be easy to determine in the morning. My guess is frame rails will be the standard 34" width. I think my old '38 tonner had a transverse front leaf and I've never owned a '40 or '41. Do they have transverse front or paralell springs?? If paralell, frames may be the same and I can help you..As soon as you can get a picture of this truck posted, we'd love to see it.
