Do you have a convertable? Many people and restoration shops weld or bolt supports in the door frames to prevent issues with 'vert's.
The rocker panels are pretty stout and you should not have saging problems. How stripped out is the unibody going to be? Just the shell or pretty complete?
My method also had the advantage that the 4x6's were down low enough that I could drop and reattach the subframe without the wood supports being in the way.
