If you have the broken tabs, there is a possibility they can be repaired. When I had my Norge, folks began finding them broke simply from removing pieces for routine reasons. As a preventive measure, I took the liquid JB Weld and filled those wells, (cavities), that put the pin in whatever alignment it needed to be in. It worked out well and I never had any trouble with them breaking.
In your case, assuming the tabs still have a little flat plastic on them, you could use masking tape to create a well, fill the well and place the tab back on top. I would be prepared to have something to hold the tab in the proper position for the needed cure time.
Food for thought.
