Been recapping the cap box, electrolytics and bakelite blocks. The box was pretty straight forward since there was fish paper around the tar block of 5 caps and it all slid right out. Here's the restuffed can.

In most cases I'm using morzh's procedure for Bakelite restuffing
Now for the technical question. (60MB Schematic.) The tube socket and tube shield base for the detector oscillator 6A7 are fastened to the chassis with two rivets. On the underside you can see a lug also fastened to the rivet on the right. This should be a ground lug (I think) BUT it is 10 ohms above chassis ground. The tube shield base is ground, the other rivet is ground so I'm guessing this rivet has some corrosion causing this (lots of corrosion on this set!)
Would you drill it out and rivet it again, run a ground wire from someplace else to it or am I missing something?
