Proper fix. Drill out the melted plastic rivets. Shim out to original height and use self tapping screws to attach the metal frame.
Design defect the 21w high filament gets hot enough to melt the plastic and the spring pressure pushes the contact away from the bulb adding resistance that causes more heat and faster melting.
It doesn't hurt to put some silver solder on the contact points but that doesn't eliminate the root cause.

Not sure why the thread revival, but I 100% agree with all that, both the cause and the best solution.
BTW, here's a direct link to post #65

On my repair journey, I first effed around with other repair attempts such as sanding, soldering, shimming, bending, cleaning, adding foil, etc. that all turned out to be temporary.
Then I did the screw repair (although the screws I used were much smaller and lower profile than the ones in that post - you need to make sure there is clearance from the bulb sockets) and that has been permanent.
