I wanted to add this pic to this thread, since the thread was such a big help to me in this repair.
Not sure if this really a better mouse trap, or if I am just over thinking things as usual.
1. Go through your office supplies @ work and find some of those file holders. The kind that you bend up to add a sheet of paper then bend back down to hold it. (free)
2. Stop by a computer repair shop and ask if they have a bin of tiny screws. (free)
3. Place a little ring of aluminum foil inside the hole of the "good" tab. Use tooth picks or a small screw driver to expand the ring out until it matches the pear/hourglass shape of the slot. Put a dab of caulk inside the foil so it will not collapse later under pressure from the JB Weld on the outside.
4. Bend a metal frame for a new tab from a piece of the file holder, temorarily secure to the broken tab with super glue. (The metal can be cut with stout sissors and bent with needle nose pliers)
5. use a Q tip to smear a light oil (to aid in removal) on the outside of the "hole form" (made in step 3 above) and put it in place. Use the remaining parts of the old hole to properly position the new hole.
6. your "mold" is now complete. Pour in JB weld.
7. Drill holes in the metal frame/plastic tab insert small screws.
8. clean up with dremmel.
In retro spect I should have compeltely covered the top surface with JB Weld. As long as the back of the new tab is flush with the rest of the body, the only point were the tab thickness matters, and fit is important, is where the hook from the housing fits in the top of the slot. The extra layer of JB Weld would have added strength without interferring with fit.
