Very interesting Hanno, I wonder where the variation occurs. The parts list description "MEMBER AND REINFORCEMENT ASSY" suggests to me it's related to riveted crossmember fishplates, rather than welded double skin midsection, which may have been present universally. In other words the siderail part may have been supplied with fishplates already riveted in place. I notice they're listed as 1st type, 2nd type, etc., which normally indicates design changes over the years. This occurred with F60S/L frames too, with late production frames featuring additional rear crossmember fishplates. I guess the only way to know is to inspect surviving vehicles. We need C15A and CGT owners to submit chassis photos for comparison.

As you point out, the rear crossmember fishplate differs on winch equipped chassis, to accommodate the rear fairlead assembly. This applies to both Ford and Chev frames.
