Early Ford V8 Rear Crossmembers

[benteight1956]

Hi, can anyone tell me if there is a difference between say a 1936 passenger car rear crossmember and a 1939 passenger one. Or between a 1936 and 1940 one. My Ford parts book which only goes up to 1938, says 1935 to 1938 are the same. What I’m looking at is depth drop, if you could call it that, from the top of the frame, at the outer edges, to the top of the centre where the U bolts go. I’ve measured up two original 1936 frames and get a drop of 136mm. Anyone have a 1939 frame they could check and anyone with a 1940 as well. Many thanks in advance.

I have some NOS crossmembers that required identification. What I learned is that 1935/1939 are flatter and have a large "48" lightly stamped by the u-bolt holes. 1940 has no marking and is taller.
