I replaced the luggage stop ends, which someone had cut up for some reason, and installed the luggage stop. Now the rear is set up correctly and is stable. I used the extra 1966 Convertible frame I have as a fixture. The next step will be to replace the rocker channel.
Step 1 was to drill out the spot welds on the old end pieces.
New pieces compared to the old. I really dont understand why someone cut the end pieces up, but i assume it was to remove the center luggage stop. They must have overlooked the 4 rivets.
New metal!!! I decided to plug weld the luggage stop in place to make it stronger instead of using rivets.
