Some good progress over the last few days.
The seat frame / top support is now fully welded in. I chose to stitch-weld rather than plug weld as it should be plug welded from the bottom (thinner metal side) but that is covered with a lot of undercoating and transferring the plug weld locations from the frame/support to the floor pans would have been a pain.
The top frame is back in place and generally aligned. Interfacing with the windshield frame looks good. so front/back and side/side of the frame is OK. I cannot count the number of times that I’ve had the top and frame in/out of this car!
There are some expected interference issues with the top frame, the interior panels, and the recent metal patchwork. Nothing a little cutting and rewelding won’t fix.
The new “Trunk Divider Bridge Support” arrived today. I cut out the spotwelds holding the pieces together. This piece should work. I just wish that I had access to a hydraulic shrinker/stretcher for forming the corners. This is heavy material. Will probably end up pie-cutting and welding to make the curves. The heavy gauge will at least make the welding easier.
