the same saggy effect can happen on the 55-59 trucks too when the original trans cross member is removed. it can be supported better with a well built "new" trans cross member that connects the upper and lower frame rails. the spreading effect of the frame rails "twisting" can affect the cab mounts and the cab because it effectively makes the mounts further apart. this can warp things and make it hard to line up door and fender gaps besides the affect it has on the floor etc.
