In order to get access to the rivets I had to remove the tuning cap.

The rivets, even the 8mm, require a washer to really pull the cap to the chassis. I use 4mm washers. Otherwise the rivets does not flare enough to hold through almost 5mm hole.
I would use the rivnuts but somehow the two cans in the middle of the chassis do not let them through.


I guess it is a good thing I ahd to removet the tuning cap: some wires are fraying and require replacement. The guy who sold it to me claimed it all works but he probably did the bare minimum.
