Agreed, if a section is open you can sub a 10 watt sand resistor dressed against the chassis and use the existing lugs as mounting terminals. But if there is a short to the chassis, or evidence ore arcing, drill the candohm out and replace all the sections. You can use one or both of the rivet holes to mount a terminal strip. Again, dress the replacements up against the chassis to help disperse heat.

Of course if there was a problem with this rather hardy component I would certainly suspect the filter capacitors, which you should replace before powering up again. Actually all the paper capacitors as well, and any other resistors much above spec.
