You see I ctt the frame right in the area where that frame bolt would end up.Here are some photos.I took all the rot out,spread the old frame a little ,slid the new trunk floor with good frame 6 inches into the old frame then welded it at the seam and then did a plug weld forward of that that can be seen in the photos. I'm thinking I want something like these adjustable units that expand to fit between the inside of the rails rather than on the bottom so I can weld it on to the old and the new frame.
