Re: picures needed
Need to dig out a truck spec. book for all the section heights. Maybe this help some. The C/40 frame rails are flat on top from just forward of the front axle centerline to the rear. Forward of the front axle centerline they drop down and in a little. Note in the the picture that the springs go from outside to under the frame rails. Also the frame section aft of the rear axle forward spring hanger tapers up from the constant section of ~9.12" to ~6.50" all the way to the end.
