The frame NOT flexing is not going to cause cracking. The inability of the cab to move independently of the frame when it does flex might, but I suspect it is just metal fatigue in an old truck.
I'd live with the crack until it becomes a real problem then stitch weld it with TIG or MIG weld with soft body panel wire. Of course you will ruin your nice paint.
