392: The angle of the rear cross member where it bends down from the top surface of the side frame rail is 20 degrees. It's hard to measure with the car body on the frame.
Here is a frame rail picture on Ebay. I hope it helps. There must be a Fordbarner who has the body off tha frame and can also tell you. All the best. JIM

Does anyone know what the rear crossmember angle is on the 35-40 cars? Thanks.
