I like Mike's (1952Cecil) solution. Nice and stiff. Although it's not dropped that much.
Carl's has a couple of hinge points that would work better if stiffened up a bit. A couple of gussets from the frame side of the plate up to the original crossmember would help immensely.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
