This is how they wear, and then they fail catistrafically. The
contact ring on the wheel wears until it develops a loose spinter
which catches in that hole, typically when you're in the middle of a
turn. At that point, you have a choice: straighten up the wheel in
spite of the ripping metal sounds coming from in there, or crash.
I've been planning to start fixing these, but I wouldn't use brass,
as what you can get is too soft and will just gall up and wear again
quickly. I would go with spring steel or stainless. Not sure which
would make the better choice, but something dissimilar to brass would
be best.
And get some lubrication in there.

Yes, these get loose, and the pot metal body doesn't take recrimping
very well. I recommend finding some narrow nylon cable ties to
tighten around them to keep them from coming apart.
You'll need a special wrench to retighten the retaining rings, that
hold those switches. There's a good deal on these on amazon.com,
serviced by airhead parts, but cheaper than at airhead.com.

The resistor started in '73. It's there so the bulb in the flasher
knob will glow slightly in the dark.
