Heater Box Repair Advice Needed

No to repairing the box.

The rivets pulled through on the driver side box 27 years ago. The heater box was just very loose but not broken apart. The doors have the metal strip at the hinge and I just copied it in sheet metal for the inside to make a sandwich. Got the right rivets and clincher tool and put them back.

I hate pop rivets...... They can be used if do not care about appearence, just use an appropriate sized star washer on the blind side before you cinch it for extra holding power.
