I'd cut the bulkhead just how the other fella did but I'd proceed to have a horizontal tube welded into place across the car in its place and then have crisscrossing triangulated tubing between that horizontal tube and the floorboard. That sort of tubing is about 2lbs per foot and I'm guestimating I'd need about 4ft across and then about 8ft for the support tubing. So, let's round up... 30lbs? Depending on the weight of the bulkhead, that'd be a neat weight-saving project.

Notice something missing...
